Acyclist rides her bike at a speed of 10 kilometers per hour. what is this speed in miles per hour? how many miles will the cyclist travel in 2 hours? in your computations, assume that 1 mile is equal to 1.6 kilometers.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

5+2x=a
