Question 495725: if you drive 100 miles and spend half the time at 45mph and half the time at 60mph how long does it take? My question is how would you set up the problem? Answer by oberobic(2304) (Show Source):
You can put this solution on YOUR website! d = rt
d = 100
.
Since you drive at two different rates, each for 1/2 the time:
.
45*t/2 + 60*t/2 = 100
.
Good luck!
