135 min

Work Step by Step

2$\frac{1}{4}$ hr = min Use a unit fraction with min (the unit for your answer) in the numerator, and hr (the unit being changed) in the denominator. Because 1 hr = 60 min, the necessary unit fraction is $\frac{60 min}{1 hr}$ Multiply 2$\frac{1}{4}$ hr times the unit fraction. 2$\frac{1}{4}$ hr =$\frac{9}{4}$ hr = $\frac{9}{4}$ hr * $\frac{60 min}{1 hr}$ = 135 min
