DIRECTIONS for the question: Solve the following question and mark the best possible option.
P is thrice as fast as Q and Q is twice as fast as R. If R can travel a distance of 250 km in 5 hours, then how much time is taken by P to cover 600 km.
A)
2 hours
B)
5 hours
C)
3 hours
D)
None of these
A
Speed of R = 250 km/5 hours = 50 kmph
Thus speed of Q = 2 × 50 = 100 kmph and speed of P = 3 × 100 = 300 kmph
Therefore, time taken by P to cover 600 km = 600/300 = 2 hours.
