Question

An electric train is moving with a velocity of 120 km/hr. How much distance will it cover in 30 sec?

Answer 1

Step 1: Given data

Velocity of the train = 120 km/h

= $120\times \frac{5}{18}m{s}^{-1}$

= $\frac{100}{3}m{s}^{-1}$

Time = 30 sec

Step 2: Formula used

$Distance=Speed\times Time$

Step 3: Finding the distance covered by the train

Putting all the values

$Distance=\frac{100}{3}m{s}^{-1}\times 30s$

$Distance=100\times 10$

$Distance=1000m=1km$

Hence the distance covered by the train is $1000m$.
