Correct Answer: Option C

Explanation:
Let duration be t hours. Distance difference = 8t - 6t = 2t = 10 km => t = 5 hours. Distance handled at normal speed (6 km/h) = 6 * 5 = 30 km.

Question #443
A motorboat tracks 36 km downstream in 3 hours and spans the same stretch upstream in 4.5 hours. Find the speed of the current.
A. 2.5 km/h
B. 2.0 km/h
C. 3.0 km/h
D. 1.5 km/h
Discuss

Correct Answer: Option B

Explanation:
Downstream speed = 36 / 3 = 12 km/h. Upstream speed = 36 / 4.5 = 8 km/h. Speed of current = (12 - 8) / 2 = 4 / 2 = 2 km/h.

Question #444
The speed of two express locomotives are in the ratio 5 : 6. If the second locomotive maps 480 km in 4 hours, find the speed of the first locomotive.
A. 120 km/h
B. 90 km/h
C. 100 km/h
D. 110 km/h
Discuss

Correct Answer: Option C

Explanation:
Speed of the second locomotive = 480 / 4 = 120 km/h. Ratio is 5:6, so 6 parts = 120 km/h => 1 part = 20 km/h. Speed of the first locomotive = 5 parts = 5 * 20 = 100 km/h.

Correct Answer: Option D

Explanation:
By 8:00 AM, Train A has run for 2 hours, covering 40 * 2 = 80 km. Remaining separation distance = 320 - 80 = 240 km. Relative speed = 40 + 60 = 100 km/h. Time after 8:00 AM = 240 / 100 = 2.4 hours = 2 hours 24 minutes. Meeting time = 8:00 AM + 2 hours 24 minutes = 10:24 AM.
