A train is moving at a uniform speed of 75 km/hr. Find the time required to cover a distance of 250 km?

A driver of a car travelling at 52 km per hour apply the brakes and accelerates uniformly in the opposite direction the car stops in 5 seconds another driver going at 3 km per hour in another car applies is break slowly and stops in 10 seconds on the same graph paper plot the speed versus time graph for the two cars which of the two cars travel father after the brakes are applied.

After covering a distance of 30 km with a uniform speed there is some defect in a train engine and therefore, its speed is reduced to 4/5 of its original speed. Consequently, the train reached its destination late by 45 minutes, had it happened after covering 18 kilometres more, the train would have reached 9 minutes earlier. Find the speed of the train and the distance of journey

A. Original speed = 10 Km/hr, Length of the journey = 90 Km

B. Original speed = 15 Km/hr, Length of the journey = 100 Km

C. Original speed = 25 Km/hr, Length of the journey = 110 Km

D. Original speed = 30 Km/hr, Length of the journey = 120 Km

A. Original speed = 10 Km/hr, Length of the journey = 90 Km

B. Original speed = 15 Km/hr, Length of the journey = 100 Km

C. Original speed = 25 Km/hr, Length of the journey = 110 Km

D. Original speed = 30 Km/hr, Length of the journey = 120 Km
