Question

A train covers 51kmvin 3hours . Calculate its speed . How far
Does the train go in 30 minutes

Answer 1

Hello mate,

Distance=51 km

Time=3 hours

Speed=?

So it is clearly that we have to find the speed of the train.

And for that we should be aware of the formula for speed.

Distance

SPEED= ------------

Time

Speed=51/3

Speed=17km/h

Now we have to find for 30 minutes.

Speed=17km/h

Time=30seconds=1/2 hours

For this we should be aware of the formula for distance.

DISTANCE=Speed×Time

Distance=17×1/2

Distance=8.5 m

Please follow me mate and mark as brainliest if you are satisfied.

It's a humble request mate.
