Given data
Train covers a distance
(S₁) = 97 Km, in time (t₁) = 4 hr
and then covers a distance
(S₂) = 63 Km, in time (t₂) = 1 hr
What is the average speed (v) = ?
The average speed of the train is the ratio of the total distance covered to the total time taken,
since total distance covered = 97 km + 63 km
= 160 Km
and total time taken = 4 hr + 1 hr
= 5 hours
Therefore,
average speed = total distance covered /total time taken
= 160 km/ 5 hr
= 32 km/hr
The average speed of the train is 32 km/hr
