Question 631553: If a car drove for 30 minutes and went 10 miles what was his average speed?
Answer by jim_thompson5910(35256) About Me  (Show Source):
You can put this solution on YOUR website!
30 min = 0.5 hours

d = rt

10 = r*0.5

10/0.5 = r

20 = r

r = 20

So his average speed is 20 miles per hour.
