Cortez Mccormick · Answer 1

140 minutes (2 hours and 20 minutes)

Step-by-step explanation:

The expression would be:

Let x = kilograms

40x + 20

substitute our value in:

40 (3) + 20

120 + 20

140 minutes

Janet Jordan · Answer 2

140

Step-by-step explanation:

First you put it into an equation (40x + 20=?)

Plug in what you know, in this case x=3.

40 (3) + 20=?

Now solve.

40 times 3 equals 120. 120 plus 20 equals 140.

40 (3) + 20 = 140
