If a train increases its speed by 20% and covers the same distance in 5 hours less, what is the original speed of the train?
A30 km/h
B40 km/h
C50 km/h
D60 km/h
Correct Answer:
C. 50 km/h
EXPLANATION
Let original speed = v km/h, original time = t hours. Distance = vt. New speed = 1.2v, new time = t-5. vt = 1.2v(t-5). Solving: t = 30 hours, v = 50 km/h.
