Question

A recording of the current weather conditions last 3/4 minute. If the recording plays repeatedly , how many times would it play in 1 hour?

Answer 1

Answer:

The recording repeated  plays 80 times in 1 hour

Step-by-step explanation:

A recording last $\frac{3}{4}$ mins

Let x be the number of times it repeats in 1 hour

Using ratio and proportion,

$1\:time=\frac{3}{4} mins\\ x\:times=1\: hour$

But $1\:hr=60\:mins$

This implies that

$1\:time=\frac{3}{4} mins\\ x\:times=60\: mins$

$\frac{3}{4}x=60$

$x=\frac{4\times60}{3}$

$x=80\:times$

Hence the recording repeatedly  plays 80 times in 1 hour

Answer 2

45 times

1 hour = 60 minutes

60 multiplied by 3/4 = 180/4 = 45
