Question

Shannon drove her car 140 miles east at a rate of 70 miles per hour. how long did she travel?

Answer 1

2 hour

Explanation:

the traveled for 2 hours to drive that distance. Using the formula D=RT, solve for T

140

70

=2 hours.

Answer 2

We know that the equation relating the three variables (distance, velocity and time) is:

velocity = distance / time

Rearranging to get time:

time = distance / velocity

So,

time = 140 miles / (70 miles / hour)

time = 2 hours
