| The average speed of a car is \[1\frac{4}{5}\] times the average speed of a bus. A tractor covers 575 km in 23 h. How much distance will the car cover in 4 h, if the speed of bus is twice the speed of the tractor? [SBI (PO) 2012] |
A) 340 km
B) 480 km
C) 360 km
D) 450 km
E) None of these
Correct Answer: C
Solution :
| Distance covered by a tractor = 575 km and time taken = 23 h. |
| Speed of tractor \[=\frac{575}{23}=25\text{ }km/h\] |
| Speed of bus \[=2\times 25=50\text{ }km/h\] |
| Speed of car \[=\frac{9}{5}\times 50=90\text{ }km/h\] |
| Distance covered by car in \[4\,h\,=90\times 4=360\,km,\] |
