If Suzan practices 10 minutes on Monday, every other day, she wants to practice two times as much as the previous day. How many hours and minutes will she have to practice on Friday?

Result

x = 2:40 (hh:mm)

Step-by-step explanation:

$$\begin{gathered} a=10\text{min}\to \text{h}=10:60\text{h}=0.16667\text{h} \\ r=2^{5-1}=16 \\ x=a\cdot r=0.1667\cdot 16=\frac{8}{3}=2.66667=2:40(\text{hh}:\text{mm}) \end{gathered}$$
