Question

Due to technical snag train travels at three forth of its usual speed how much longer will it take to cover distance that it normally covers in 1 hour

Answer 1

Let the initial speed of train is ‘x’ km/h

time taken to reach the destination point= 1 hour

so, distance travelled by train = x km

a/c to question,

due to technical snag, speed of train reduced to 3/4th of its usual speed.

so, the speed of train = 3x/4 km/h

distance travelled by train = initially distance travelled by train = x km

so, time taken = distance travelled/speed of train

= x/(3x/4) = 4/3 hours.

hence, time is 4/3 hours.
