Question

train is running at 26 km/hour. if it cross a pole in 25 second ,find its length.

Answer 1

Given speed = 60 km/hr.

60 km/hr = (60*1000 m) ÷ (1*3600 s)

=16.666 m/s

So the pole travels 16.66 m in 1 sec. Thus the distance travelled by the pole in 9 sec (i.e., the length of the train) = 16.666*9

=149.994 m (almost 150 m)

Answer 2

Speed of Train = 26 km/hr

= 26 × 1000/3600 = 65/9 m/s = 7.22m/s

And time = 25 sec.

Speed = Distance/Time

So, Distance = Speed × Time

Length of Train = 7.22 × 25

= 180.5 m

ThankYou!!!
