The Problem

Rene is going to the lake to visit some friends. If the lake is 60 miles away, and Rene is driving at 40 miles per hour the entire time, how long will it take her to get to the lake?

Answer provided by our tutors

Let

S = 60 miles is the distance that Rene needs to drive

v = 40 miles per hour is her speed

t = the time she needs to get to the lake

We need to find t.

Using the formula for speed v = S/t we can write the following for t

t = S/v that is

t = 60/40

t = 1.5 hours

Rene needs 1.5 hours to get to the lake.
