Step-by-step explanation:

60 seconds = 1 minute

I droplet = 20 seconds

60seconds ÷ 20 seconds = 3

3 droplet =1 minute

5 minutes = 3 × 5 =15

Answer 2

Answer:

There will be 15 droplets of water in 5 minutes.

Step-by-step explanation:

1:20 = one droplet dropping at a rate of 20 seconds.

5 minutes = 60 x 5 = 300 seconds

1/20 = x/300

20x= 1 x 300

20x = 300

20x/20 = 300/20

x = 15

Hence, in 300 seconds, or 5 minutes, 15 droplets of water will fall already.
