Excluding minor platform corridor stops, the speed of an express route train is 84 km/h, and including stops it tracks at 70 km/h. How many minutes does it spend resting at stops per hour? MCQ with Answer and Explanation

Excluding minor platform corridor stops, the speed of an express route train is 84 km/h, and including stops it tracks at 70 km/h. How many minutes does it spend resting at stops per hour?
A. 10 minutes
B. 8 minutes
C. 12 minutes
D. 15 minutes
Answer: Option A
Solution (By JKSSB Mock Tests)
Stoppage time per hour = (84 - 70) / 84 = 14 / 84 = 1/6 hour. In minutes = (1/6) * 60 = 10 minutes.

A train passes a static milepost in exactly 7 seconds. If the speed of the train is 72 km/h, find the absolute length of the train.
A. 180 meters
B. 140 meters
C. 120 meters
D. 160 meters

Correct Answer: Option B


Explanation:
Speed of train = 72 * (5/18) = 20 m/s. Length of train = Speed * Time = 20 * 7 = 140 meters.

Question #2
A motorboat covers 24 km downstream in 1.5 hours and covers the same distance upstream in 3 hours. Find the speed of the boat in still water.
A. 12 km/h
B. 14 km/h
C. 10 km/h
D. 15 km/h

Correct Answer: Option A


Explanation:
Downstream speed = 24 / 1.5 = 16 km/h. Upstream speed = 24 / 3 = 8 km/h. Speed in still water = (16 + 8) / 2 = 12 km/h.

A. 12 km/h
B. 11 km/h
C. 14 km/h
D. 13 km/h

Correct Answer: Option A


Explanation:
