Question

A firefighter has to get to a burning building as quickly as he can. There are three paths that he can take. He can take his fire engine over a large hill (5 miles) at 8 miles per hour. He can take his fire engine through a windy road (7 miles) at 9 miles per hour. Or he can drive his fire engine along a dirt road which is 8 miles at 12 miles per hour. Which way should he choose? Select the correct answer from above options

Answer 1

To reach the destination quickly, the fire fighter has to calculate the time required on the basis of given data. Driving his fire engine 5 miles at 8 miles per hour takes 37.5 minutes. Driving his fire engine 7 miles at 9 miles per hour takes about 47 minutes. Driving his fire engine 8 miles at 12 miles per hour takes 40 minutes So he should choose to drive his fire engine over the hill.
