Respuesta :

The measure of the speed during the time is 63. 64 miles per hour

How to determine the speed

The formula for speed is expressed as;

Speed = distance/ time

Given that;

  • Distance traveled = 21 miles
  • Time = 20 minutes

Let's convert the time in minutes to hour

60 minutes = 1 hour

20 minutes = x hour

cross multiply

x = 20/ 60

x = 0. 33 hours

Substitute the values

Speed = 21/ 0. 33

Speed = 63. 64 miles per hour

Thus, the measure of the speed during the time is 63. 64 miles per hour
