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 pexercises per hour, what was her average rate the next day, in terms of p?

Answer 1

P- it is amount of exercises
average= $\frac{exercises}{hour}$
Monday average= $\frac{p}{3h}$
Tuesday average= $\frac{p}{2h}$
If we take into account both days and calculate average from Monday and Tuesday ( we sum 3h on Monday and 2 hours on Tuesday and p exercises on Mon and p exercises on Tuesday):
Monday and Tuesday average=$\frac{2p}{5}$
