Question

The formula d = rt gives the distance traveled in time t at rate r. A bicyclist rides at a constant rate of 15 miles per hour. How many miles will he travel in 3.5 hours?

Answer 1

d=rt
distance = rate*time
rate=15mph
time=3.5hours
distance = 15*3.5 = 52.5
He will travel 52.5 miles in 3.5 hours assuming his rate does not change.
