Distance Calculation | MCQs

Explanation

Man climbs 20 yards and slips down 5 yards in one minute

i.e. he climbs (20-5 = 15 yards) in one minute.

But in the last minute, he will be climbing 20 yards as he gets on the top so no slip.

Time taken to climb 80 yards = 60/15 + 1

                                                   = 5 minutes.

He climbs the hill in 5 minutes

Explanation

To find the farthest number from -1 on the number line:

-1 is the reference point.

-10 is 9 units away from -1.

10 is 11 units away from -1.

5 is 6 units away from -1.

Since 10 is the farthest (11 units away), the correct answer is: 10
