Question

Aaj train hundred metre long and is moving with a uniform velocity of 54 km per hour the time taken by it to cross the bridge 150 metre long is

Answer 1

Explanation:

length of train= 100metre

time taken by train per hour=54kilometre

Length of bridge=150metre

We know that,1 km =1000m

54 km =54×1000=54000metres

150-100 =50metres

54000- 50 = 53995metres

time taken by train per metre=54/1000=9/10hours
