A cyclist rides his bike at a speed of 18 miles per hour. What is this speed in kilometers per hour? How many kilometers will the cyclist travel in 3 hours? In your computations, assume that 1 mile is equal to 1.6 kilometers. Do not round your answer.

Well, if 1 mile = 1.6 kilometers and he's traveling at 18mph, then do 18 x 1.6 which = 28.8.

So, this is his current speed in kph

3 x 28.8 = 86.4‬

They will have traveled 86.4‬ kilometers

(I haven't worked with this kind of math in a while so correct me if I'm wrong!)
