Answer 1

See Explanation

Explanation:

The question is incomplete, as the number line is not given. The general explanation is as follows;

First, record the time she hung up (say, time = x)

To rewind 15 minutes back means, x - 15

So, point on the number line will be x - 15

Take for instance

`x = 45`

The point on the number line will be:

`x - 15 = 45 - 15`

`x - 15 = 30`
