Question

Imelda needs to convert 440 centimeters per minute to meters per hour. Which conversion factors should she use?

Answer 1

`440 (cm)/(min) * (1~m)/(100~cm) * (60~min)/(1~hr) =`


`= 440 (cm)/(min) * (60~m * min)/(100~cm * hr)`


`= 440 (cm)/(min) * (3~m * min)/(5~cm * hr)`

Multiply cm/min by 3/5 to get m/hr.
