Q.
Two motorcycles, M and N, start from points 480 km apart. They travel at constant speeds. If they move towards each other, they meet in 5 hours. If they move in the same direction, they meet in 15 hours. What is the speed of motorcycle M? (Assume M is the faster motorcycle)
A
a) 55 km/h
B
b) 64 km/h
C
c) 70 km/h
D
d) 80 km/h
Correct Answer: Option B)
Detailed Step-by-Step Explanation:
Relative speed: opposite = X + Y = 480/5 = 96 km/h. Same direction = X – Y = 480/15 = 32 km/h. Solving: X = (96 + 32) / 2 = 64 km/h.
