Question

6. A long-distance runner travels a distance of 108 km in 8 hours.
What is his average speed?

Answer 1

13.5 km/hr

Explanation:

speed= distance÷time

s=108÷8

s=13.5 km/hr

Answer 2

That is the sort of question an 8-year-old might be asked to solve because it is so simple. time= 3 1/3 hrs to travel 100km, 1/3 of an hour is 20 minutes.
