Question

A flashlight flashes every 45 seconds. After 10 ½ minutes, how many times does the light flash?

Answer 1

14

Explanation:

Answer 2

14 flashes.

Explanation:

1 minute = 60 seconds

x minutes = 45 seconds.

1/x = 60/45 Cross multiply

60x = 45 Divide by 60

x = 45/60

x = .75

10 1/2 minutes = 10.5 minutes.

x flashes / 10.5 minutes = 1 flash / 0.75 minutes Multiply by 10.5

x = 10.5/0.75

x = 14
