Question

A TRAIN 250MTS LONG IS RUNNING AT A SPEED OF 120KM/HR HOW MUCH TIME WILL TAKE TO CROSS ELECTRIC POLE IN SECONDS?????? ​

Answer 1

Step-by-step explanation:

Answer

Speed = Distance/time

Speed = 120 × 5/18 = 600 /18 = 100/3 m/sec

Distance = 250 m

Time = Distance / speed

Time = (250 ×3)/100

Time = 30/4 = 15/2 = 7.5 sec

Time = 7.5 sec

Answer 2

$\huge\boxed{\fcolorbox{springgreen}{grey}{solution:-}}$

Speed = Distance/Time

m/s=5/18

,speed=120×5/18=600/18=100/3m/s

Distance=250m

Time=250×3/100

Time=2.50×3=7.5seconds

Therefore,time taken to cross pole is 7.5seconds
