Question

Jim ran four-fifths of a mile and dropped out of the race. His pace was 12 miles per hour until the point he dropped out of the race. How many minutes did he run?

Answer 1

Find time needed for 4/5 mile:
12 miles = 1 hour

1 mile = 1/12 hour

4/5 mile = 1/12 x 4/5 = 1/15 hours

Convert hour to min

1/15 hour = 1/15 x 60 = 4 mins


Answer: He ran for 4 minutes
