The Murphy family just drove 300 miles to visit their grandparents. Mr. Murphy drove

Question

70 mph for 65% of the trip and
35 mph or less for 20% of the trip that was left. Assuming that Mr. Murphy never went over 70 mph, how many miles did he travel at a speed between 35 and 70 mph?

I can't remember the formula, we did this a couple of years ago

Answer 1

distance at 70 mph = .65(300) or 195 miles

trip left = .20(105) = 21 miles

distance traveled between 35 and 70 = 300-195-21 = 84
