Question

Solve find the ratio of the time taken by the minute hand to complete 2 rounds to the time taken for the hour hand to complete 1 round

Answer 1

Answer:

1 : 6

Step-by-step explanation:

Let us take a common unit: minute.

Time taken by the minute hand to complete 2 rounds = 120 minutes

(1 round = 60 minutes, so 2 rounds is 60+60 = 120)

Time taken by the hour hand to complete 1 round = 12 hours = 12*60 = 720 minutes

∴ Ratio = 120 minutes : 720 minutes

120 : 720

12 : 72

1 : 6

Therefore, the ratio is 1 : 6.
