Answer 2

A) The width is 12 cm; the average time is 3 minutes

Explanation:

`(5)/(3)= (20)/(y)`

Cross multiply.

5 × y = 3 × 20

5y = 60

5y ÷ 5 = 60 ÷ 5

y = 12

The width is 12 cm. Moving onto the time.

`(12)/(4) =(y)/(1)`

Cross multiply.

4 × y = 12 × 1

4y = 12

4y ÷ 4 = 12 ÷ 4

y = 3

The time is 3 minutes.
