Question #1
A man can walk at 6 km/h. After every kilometer, he takes a rest of 6 minutes. How much time will he take to cover a distance of 18 km?
A. 4 hours 30 minutes
B. 4 hours 42 minutes
C. 4 hours 48 minutes
D. 5 hours

Correct Answer: Option B


Explanation:
Pure walking time = 18 / 6 = 3 hours. Number of rest intervals = 18 - 1 = 17 intervals. Total rest time = 17 * 6 = 102 minutes = 1 hour 42 minutes. Total time = 3 hours + 1 hour 42 minutes = 4 hours 42 minutes.

Question #3
A train covers a distance between two stations in 45 minutes. If its speed is reduced by 5 km/h, it covers the same distance in 48 minutes. Find the distance between the two stations.
A. 50 km
B. 60 km
C. 80 km
D. 72 km

Correct Answer: Option B


Explanation:
Let initial speed be s. Distance is constant, so s * (45/60) = (s - 5) * (48/60) => 45s = 48s - 240 => 3s = 240 => s = 80 km/h. Distance = 80 * (45/60) = 60 km.
