A bus moving at 40 km/h covers a distance in 6 h 15 min. If it travels the same distance at 50 km/h, then how long will it take to cover the distance? [SSC (CPO) 2015] |
A) 4 h
B) 2 h
C) 5 h
D) 6 h
Correct Answer: C
Solution :
\[\therefore \] Distance = Speed \[\times \] Time \[=40\times \left( 6+\frac{15}{60} \right)\] |
\[=40\times \left( 6+\frac{1}{4} \right)=40\times \frac{25}{4}=250\,km\] |
\[\therefore \] \[\text{Time}=\frac{\text{Distance}}{\text{Speed}}=\frac{\text{250}}{\text{50}}=\text{5h}\] |
