Question

Kendra rides a bicycle on a path that is 54 miles. Her average speed is 9 miles per hour. To find about how long the trip takes, solve the distance formula d=rt for t. Then substitute to find the time the trip takes

Answer 1

t = d/r

6 hours

Explanation:

distance = rate * time

d = rt

Solve for t. Divide both sides by r.

d/r = t

t = d/r

d = distance = 54 miles

r = rate of speed = 9 miles/hour

t = (54 miles)/(9 miles/hour)

t = 6 hours

Answer 2

6 hours

Explanation:

54miles/9mph=6 hours time traveled

or 12 hours round trip
