p- it is amount of exercises average= [latex] \frac{exercises}{hour} [/latex] Monday average= [latex] \frac{p}{3h} [/latex] Tuesday average= [latex] \frac{p}{2h} [/latex] 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=[latex] \frac{2p}{5} [/latex]
