One of my physics teachers taught us this simple rule- 60 mph is 88 feet per second. We used this in half of the problems we did, so it was worth memorizing. We derived it once, just to validate it, but it's true. And once you've got that, it's easy to convert to 30, 45, 10, whatever, mph.

30x5280÷60÷60=44ft/sec
First find total feet per hour, then divide the total feet by 60 to convert the total miles per hour into miles per minutes. Then divide total miles per minute by 60 to find total miles per seconds.

[russelllomando]

got it. multiply for seconds in an hour & divide into 30 miles of feet. thanks for the fun.

[thomasharding]

It is good that you listed the mile to feet conversion for your Metric viewers.

[RichaRat]

That was too easy. Everybody just knows 60mph is 88ft per second from seat belt commercials! LOL

This 60+ yo gma solved it correctly- chalk it up to my amazing hs chemistry/physics teacher who drilled us on conversion equations from day one. (Also, I achieved the top math student award in my graduating class.)

Easy 44 ft/sec

First of all work out how many seconds in a hour 60 x 60 = 3600

5280 ft x 30mph = 158400 ft / 3600 = 44.

Your lesson shows how it's done. A short cut is to memorize the constant 1.466667 (as many decimal places as you wish). Speed (mph) x = Speed (fps). The constant is derived from dividing the feet in 1 mile (5280) by the number of seconds in 1 hr (3600). If you want feet per minute, just divide by 60 instead of 3600. Been using that formula as one factor in coordinating traffic signals.

[alanknollmeyer]

or for a general hack, just multiply the mph by 1.5 and you get a pretty close approximation.

[devonwilson]

Greetings. The answer is 44 ft/sec and this is how we have determined it. We use the formula D =VT. Thereafter, we convert miles to feet and minutes to seconds to get
V=(30×5, 280)/(60×60)ft/sec. The answer is V= (528)/(12) =
(4×132)/(4×3)=(132)/(3)=44 ft/sec.

A nautical mile applies to land and sea. It is 1min of latitude and is 6080 ft

[mr.x]

44, But if this is incorrect it's because I'm going a mile a minute.

[fraram]

I'm not a hater but your method to solve this 20 seconds math problem, made me hate math problems.
Congratulations now you broke a world record on who takes more time to solve a Math problem

[Frie_Jemi]

1 mph is equal to 5280 ft. in 60 minutes or 3600 seconds.
(5280/3600) 52.8÷36 so to get 30 mph you multiply by 30. Instead of divide by 36 then multiply by 30. First do (36÷30=1.2) AND. 52.8÷1.2=44

[bobcornwell]

The answer is 44 or very close to that. 1 mph is approximately 1.467 ft/sec.

[Briarbuddy]

Takes 10 seconds to figure it out. Not 23 minutes

[truxton]

44, found the answer in 20 seconds, mainly in my head just had to divide 1/2 mile in feet by 60 to get the answer, really people struggle with this??

[KW-gbcd]

Among other things, this video is a good argument for switching to the metric system.

[KDFantastic]

It is so simple. Your explanation is more confusing. All I did was multiply 30 miles × 5280 ft = 158, 400 ft ÷ 60 minutes = 2, 640 ÷ 60 seconds = 44. No need for complicated comps as long as you understand the question.

"MANY WILL GET WRONG"

I hate that. How about saying, "This one might be challenging" ?

It's 44 ft/s, but why the assumption about "MANY" ?

It's a statement designed to bully people into wanting to learn your methods because who wants to be one of the MANY who get things WRONG? And the rest fall into the, "Yeah, but math is hard so who cares" category, or those who take up the challenge to prove they "already know it."

Try again. Show your potential students that math is like any other language; always within reach. It's about practice, determination, and most of all, it's about having fun while learning it.

Stop with the "MANY WILL GET WRONG".
