Question

the distance between two places X and Y is 500 kilometre to buses started from the points X and Y at the same time but in opposite direction on parallel roads after running five five hours is found at the distance between the buses is 50 km find the speed of each bus if one bus moves 10 kilometre per hour faster than other​

Answer 1

Answer:

100km/h & 90 km/h

Step-by-step explanation:

total distance = 500km

total time = 5 hrs

so, av. speed for the bus which completes 500km at 5h is 500/5 = 100km/h

and av. speed for the bus which is 50km behind is 500-50km at 5h is 450/5 = 90km/h.

Thus, faster one is 100-90 = 10km/h faster
