Answer

Ans : = $\frac{9}{2}$

Work Step by Step

3 Hours to 40 minutes. First Write the ratio and divide the common units: So, $\frac{3 hours}{40 Minutes}$ Now find the lowest term $\frac{3 hours}{40 Minutes}$ = $\frac{3 \times 60 minutes}{40 Minutes}$ (As 1 hr = 60 mins) = $\frac{180 minutes}{40 Minutes}$ = $\frac{180}{40}$ (Common units) = $\frac{180 \div 20}{40 \div 20}$ = $\frac{9}{2}$
