# Math Help - Kmph to mph question. I didn't know where this should go

1. ## Kmph to mph question. I didn't know where this should go

Can a mod please move this to the appropriate subforum?

Jodie travels at a speed of 80 km per hour for 2 hours 45 minutes. Work out how many miles she drives.

I understand 5 miles = 8 km but I don't know how to solve the question.
Sorry for my noobishness, thanks for the help!

(80 km/hr)(2.75 hr) (5 mi/8 km)

?

Let's try it by writing it this way.

$\text{80 km/hr} = \frac{80~km}{1~hr}$

$\left ( \frac{80~km}{1~hr} \cdot \frac{2.75~hr}{1} \right ) \cdot \frac{5~mi}{8~km}$
