Question

A train travels at a speed of 70km/h and travels a distance of 630 km. How long did it take the train to complete its journey?

Answer 1

9 hr

Step-by-step explanation:

Speed = distance/time

Let the time taken by the train be t.

=> 70 = 630/t

=> t = 630/70

=> t = 9

it take 9 hr to complete its journey

Answer 2

9 hours

Step-by-step explanation:

Using the formula to solve motion problems: d=r*t (Distance = Rate * Time)

Given:

Distance = 630 km

Rate (Speed) = 70 km/h

Time = Distance / Time

Time = 630/70

= 9
