Question

Tom can inflate 20 basketballs in 16 minutes . He concludes that if the total number of basketballs he can inflate, b, is proportional to the number of minutes

Answer 1

Explanation:

Step one:

given

we are told that tom can inflate 20 basketballs in 16 minutes

hence in one minute, he can inflate 20/16

= 10/8= 5/4 basketballs per minute

the rate at which he inflate the ball is 5/4 ball per minute.

The total number b is proportional to the number of minute

`b\alpha t`
