Question

the distance between two stations is 210 km . how much time will it take to cover the distance at an average speed of 7 km/h​

Answer 1

Solution:

Speed = (Distance travelled) / (Time)

= (240 km) / (4h) = 60 Km/h

Therefore the speed of the train is 60km/hr.

Answer 2

Answer:

To cover 210 km distance, at an average speed of 7 km/h​ will take 30 hours.

Explanation:

Given

Distance between two stations(d)=210 km

Average speed(s)=7 km/hr

To calculate how much time(t) will it take to cover the distance

Solution:

Use the formula of speed

$Speed(S)=\frac{Distance traveled}{Time taken}$

Putting the values, we get

$7=\frac{210}{t} \\\\7xt=210\\\\t=\frac{210}{7} \\\\t= 30 hr$

Thus, it will take 30 hours to cover the distance.
