Question

a train is moving at a uniform speed of 75 km per hour how far will it travel in 20 minutes find a Time required to cover a distance of 250 km

Answer 1

For First Condition

Time = 20 min = 1/3 Hour
Speed = 75 km/Hour

1. Speed = Distance / Time
Distance = Speed * Time
                = 75 * 1/3
Distance = 25 Km

For Second Condition

Speed = 75 km /Hour
Distance = 250 Km

2. Speed = Distance / Time
    Time = Distance / Speed
             = 250 / 75
             = 3 1/3 Hours
    Time = 3 Hours 20 Min
