If a man walks at 14 km/h instead of 10 km/h, he would have walked 20 km more. What is the actual distance traveled by him? MCQ with Answer and Explanation

If a man walks at 14 km/h instead of 10 km/h, he would have walked 20 km more. What is the actual distance traveled by him?
A. 50 km
B. 70 km
C. 40 km
D. 60 km
Answer: Option A
Solution (By JKSSB Mock Tests)
Let the time taken be t hours. Distance difference = 14t - 10t = 4t = 20 km => t = 5 hours. Actual distance = 10 * 5 = 50 km.

Question #1
The speeds of two parallel running trains are in the ratio 5 : 4. Moving in opposite directions, they take 6 seconds each to pass a stationary signal post. Find the total time they take to cross each other completely.
A. 7.2 seconds
B. 6.0 seconds
C. 5.4 seconds
D. 6.6 seconds

Correct Answer: Option B


Explanation:
Let the speeds be 5x and 4x. Length of first train = 5x * 6 = 30x. Length of second train = 4x * 6 = 24x. Total passing distance = 30x + 24x = 54x. Relative speed = 5x + 4x = 9x. Time taken to cross each other = 54x / 9x = 6 seconds.

Question #2
The speed of a boat in still water is 14 km/h and the speed of the current is 4 km/h. How much distance can the boat cover upstream in 2 hours?
A. 22 km
B. 24 km
C. 20 km
D. 18 km

Correct Answer: Option C


Explanation:
Upstream speed = 14 - 4 = 10 km/h. Distance covered in 2 hours = 10 * 2 = 20 km.

Question #3
A train 180 meters long is running at a speed of 90 km/h. How long will it take to pass a post?
A. 8 seconds
B. 9 seconds
C. 7.2 seconds
D. 6 seconds

Correct Answer: Option C


Explanation:
Speed = 90 * (5/18) = 25 m/s. Time to pass a post = 180 / 25 = 7.2 seconds.
