Question

A motorist travels 160 km at 80 km/h and 160 km at 100 km/h. What is the average speed of the motorist for this trip?.

Answer 1

Analyze problem

since the distance is the same, we will not need to do any solving in that part

so, the average of 80 and 100 is

(80+100)/2

which is 90

so, 90 miles per hour
