A cyclist rides her bike at a rate of 8 miles per hour.

What is this rate in kilometers per hour?
How many kilometers will the cyclist travel in 4 hours?
In your computations, assume that 1 mile is equal to 1.6 kilometers.
Do not round your answers.

Answer

1 mile is equal to 1.6 kilometers, so 8 miles (using a direct proportion) should be equal to 8 * 1.6 = 12.8 kilometers.
The cyclist rides at 12.8 kilometers per hour.
In four hours, the cyclist would have rode 12.8 * 4 = 48 + 3.2 = 51.2 kilometers.
