The average of a car is $1\frac{3}{5}$ times the average of a bus. A tractor covers 1150 km in 23 hours. how much distance will the car cover in 4 hours if the speed of the bus is twice the speed of the tractor ?

640 km

Speed = \(\frac{DIstance}{Time}\)

Speed of tractor = \(\frac{1150}{23}\)  = 50 km/h

Speed of Bus = 2 × 50 = 100 km/h

According to question ,

Speed of car = \(\frac{8}{5}\) × Speed of Bus

So , Ratio of speed of Bus & Car = 8 : 5

5R = 100

1R = 20 km/h

8R = 8 × 20 = 160 km/h

Distance covered by Car = 160 × 4 = 640 km
