A train travels 97 kilometers in 4 hours, and then 63 kilometers in 1 hours. What is its average speed?

Answer?

units?

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
