Question

find the time in which a train of length 132 M will cross and electric post if the speed of the train be to 6.4 km /hour​

Answer 1

It will take the train 1.2375 minutes to pass the tunnel

Explanation:

Mathematically, we know that ;

time = distance/ speed

The distance here is the length of the train which is 132 m ; we can convert this to km by dividing by 1000

We have this as 132/1000 = 0.132 km

So, we have the time as;

0.132 km/6.4 km/hr = 0.020625 hr

Mathematically, we know that 60 minutes make an hour;

so we have

0.020625 * 60 = 1.2375 minutes
