Question

A car traveling at an average rate of 55 km per hour made a trip in 6 hours. if it had traveled at an average rate of 50 km per hour, the trip would have taken how many minutes longer?

Answer 1

The total trip at 55 km per hour is 55 km per hour x 6 hours = 330 km.

Total time for the rip at 50 km per hour is 330 km / 50 km per hour = 6.6 hours.

1 hour = 60 minutes. 60 minutes x 0.6 hours = 36 minutes loner.
