Answer:

if you are asking a real question the answer should be on your driving history on life 360 or maybe the average gps. How fast were you driving? I have no idea thats a answer only you know.

Answer:

r = 70.59 miles / hour

Explanation:

Comment

The first set of numbers gives you the distance you travelled.

Givens

t = 20 minutes = 20/60 = 1/3 of an hour

r = 60 miles / hour

d = ?

d = r * t

d = 60 * 1/3

d = 20 miles (The hours cancel)

So now you can find out what 17 minutes means

d = 20 miles

t = 17 minutes = 17/60 hours = 0.2833 hours.

r = d / t

r = 20 / 0.2833

r = 70.59 miles / hour
