Question

The average speed if a train is 3 times the average speed of a car.
The car covers a distance of 520 kms in 8 hours. How much
distance will the train cover in 13 hours?​

Answer 1

Solution

Let speed of train be x and speed of car be y.

Car covers 520km in 8 hrs, it's speed= 520/8= 65km/hr

Speed of train = 3 * 65= 195km/hr

Distance covered by train in 13 hrs = 13*195= 2535km

Hope this helps you!!

Answer 2

Let the average speed of train be 3x

Let the speed of car be x

Speed of Car = Total Distance Travelled/Time = 520/8 =65

So the speed of train = 3*65=195 km/h

Distance Travelled By Train = Speed * Time = 195*13 = 2535 km

Hope it helps!
