How to work out upper and lower bounds 3 - GCSE question grade 7+

@3minutemaths for quick reminder and GCSE maths walkthrough videos.


This video is all about how to work out upper and lower bounds and forms part of the playlist of the same name.

The question is aimed at around grade 6+ GCSE maths:

In the formula D=ST
S = 15.93 correct to 2 decimal places
T = 1.556 correct to 3 decimal place
Calculate the upper bound for D. Give your answer to 3 decimal places.

The formula looks suspiciously like a rearranging of S = D/T (Speed = Distance / Time.)


I hope the video helps and please do leave a comment - thanks!
