Test: Clocks- 2 - Question 9

Find the time between 4 and 5'o clock, when the two hands of a clock are 4 minutes apart?

Detailed Solution for Test: Clocks- 2 - Question 9

At 4 o' clock, the hands are 20 minute spaces apart.

To get the first 4 min spaces between the hands ,the minute hand has to gain 20 - 4 = 16 minute spaces over the hour hand.

To get the second 4 min spaces between the hands ,the minute hand has to gain 20 + 4 = 24 minute spaces over the hour hand.

In 60 minutes, minute hand gains 55 minute spaces over the hour hand.

Time taken for gaining 16 minute spaces by minute hand
