Step-by-step explanation:
Given the ratio of speed of a car, a truck and a bus is 5:2:3.the average speed of the car, truck and a bus together 60 km/hr. what is the average speed of car and truck .
- So the ratio of speed of car, truck and bus is in the ratio 5:2:3
- So let the speed of car, bus and truck be m km/hr
- So it will be 5m, 2m, 3m
- Now the sum will be 5m + 2m + 3m = 10 m km/hr
- So average speed will be 10 m / 3
- According to the question average speed is 60 km/hr
- So 10 m / 3 = 60
- 10 m = 180
- m = 180 / 10
- Or m = 18
- Now the average speed of car and truck will be
- 5m + 3m / 2
- 8m / 2
- = 4m
- Or 4 x 18
- = 72 km / hr
