Question

On Monday,it took Helen 3 hours to do a page of science homework exercises.The next day she did the same number of exercises in 2 hours. If her average rate on Monday was p exercises per hour what was her average rate the next day .In terms of p?

Answer 1

Answer:

It's 3/2p!

Step-by-step explanation:

Because Helen do the same number of exercises on 2 days, the time to do and the average rate are  inversely proportional!

So, if on Monday, Helen's average rate is p then on the next day, her average rate is:

p × 3 ÷ 2 = $\frac{3p}{2}$

=3/2p
