Question

Charlemagne’s column covers the first 12 miles in 4 hours. He then increased the speed by 2 miles per hour. If the total distance of the trip was 52 miles how long did it take to finish the trip

Answer 1

12 miles in 4 hours is 3 mph

52-12=40 miles left

40 miles at 5 mph would take 8 hours

8+4=10

it took 10 hours to finish the trip.
