A car is traveling at a speed of 50 kilometers per hour. What is the car's speed in miles per hour? How many miles will the car travel in 4 hours? In your computations, assume that 1 mile is equal to 1.6 kilometers. Do not round your answer.

I came up with
Speed : 5 mi/h
Distance 300 mi

But that's wrong apparently.

speed 75* is what I came up with lol not 5.

$$50km*\frac{1mi}{1.6km}=31.25mi/h$$
Notice how both "km"s cancel, (km/km=cancels its self out) leaving miles.
So based on that, how far would it travel?
