Question

A train covers d miles the first hour, e miles the second hour and f miles the third hour what is the average rate for the entire trip?

Answer 1

Answer:

(d+e+f)/3

Step-by-step explanation:

the total distance covered by the train is d + e + f.

The time taken by the train to complete the journey is 3 hours.

so by the formula of average velocity which is (total distance covered by the body)/(total time taken by the body to complete the journey)

applying this we get

d + e + f /3
