| A car covers a distance of 528 km in a certain time at a speed of 66 km/h. How much distance would a truck cover at an average speed which is 24 km/h less than that of the speed of the car in time which is 7 h more than that taken by the car? [IBPS RRB (Office Assistant) 2012] |
A) 336 km
B) 682 km
C) 598 km
D) 630 km
E) None of these
Correct Answer: D
Solution :
| Case I Time taken by car \[=\frac{528}{66}=8\,\,h\] |
| Case II Time\[=15\,\,h\] |
| Speed \[=66-24=42km/h\] |
| \[\therefore \]Distance covered by truck \[=\text{Speed}\times \text{Time}\] |
| \[=42\times 15=630\,\,km\] |
