Question

When a person leaves his home for sightseeing by his car, the meter reads $12352km$. When he returns home after two hours the reading is $12416km$.
What is the average speed of the car during the period measured in $km/hr$?

Answer 1

$d_1=12352$ Km

$d_2=12416$ Km

$time=2$ hr

(a) The average speed is the ratio of the total distance to the total time taken:

$Avg.speed=\frac{12352-12416}{2}=32Km/Hr$
