Question

The train ride at the zoo covers a distance of 7 and 5/6 miles in 4/5 of an hour. How many miles per hour does the train go?

Answer 1

The speed of the train in miles per hour which is the ratio of the total distance covered and the total time taken to cover the distance is 9.79 mph

• Total distance covered = 7 and 5/6 miles = 7.83333 miles
• Total time taken = 4/5 of an hour = 0.8 hour

Recall :

Speed in miles per hour = Distance covered / time taken

• The speed of the train = 7.833333 ÷ 0.8 = 9.7916

• The speed of the train in miles per hour = 9.79 mph

Therefore, the speed of the train in miles per hour as calculated from the distance covered by the train over a certain period of time is 9.79 mph
