Respuesta :

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

Answer:

2 hour

Step-by-step explanation:

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

140

70

=2 hours.
