Worded Inverse Proportion & Rates - Part 3 | GCSE Maths Pro

In this video we go through the third part of proportion which is specifically worded inverse proportion and rates of work. This is where we use the logic of inverse proportion to figure out problems such as if it takes for 5 taps to fill a pool, how long would it take for 2 taps to fill the pool. You do not need to have seen the first 2 videos to watch this one. This also includes answering the part b question about what assumptions we make.
