Answer 2

Given:

The speed of magnetic audiotape is 4.5cm/s

Duration of cassette=60 minutes

To find:

The length of the magnetic audiotape

Solution:

The length of the magnetic audiotape is 16,200 cm.

We can find the length by following the steps given below-

We know that the length of the tape is the product of the speed and duration of the cassette.

The length of the tape= Speed of the tape×duration of the cassette

The speed of the tape is 4.5 cm per second.

The total duration of the tape=60 minutes

Since 1 minute has 60 seconds, the duration in seconds will be 60×60=3,600 seconds.

The length of the tape=4.5×3600

=45×360

= 16,200 cm

Therefore, the length of the magnetic audiotape is 16,200 cm.
