A 45 min tape plays at the speed of 1.88 in/s. How long is the tape in meters? One inch is equal to 2.54 cm.

128.93m

Explanation:

We are told that a 45 min tape plays at the speed of 1.88 in/s. First we need to convert 45 mins to seconds. This will be: = 45 × 60 = 2700 seconds.

Therefore, the tape will use:

= 2700 × 1.88inch

= 5076 inch

Since 1 inch = 2.54cm

5076 inch = 2.54 × 5076 = 12893.04cm

Note that 100cm = 1m

We will then convert 12893.04cm to m. This will be:

= 12893.04cm / 100cm

= 128.9304m

= 128.93m
