Question

Mario and Whitney have got married. On their honeymoon they drive 30 km in 15 minutes. What was their average speed in km/h?

Answer 1

Answer:

The average speed is 120 km/h.

Explanation:

Average speed is defined as the ratio of the total distance covered to the total time taken.

Average Speed = Total Distance Covered ÷ Total Time Taken

Here total distance covered by the couples is 30 km in 15 mins. To calculate the speed in km/h we need to convert the time into hours from minutes.

15 mins = 15 ÷ 60 = 0.25 hrs

∴ Average Speed = 30 km ÷ 0.25 hrs = 120 km/h
