Question

If John makes $20 an hour, how long will it take him to make $140? Question 3 options: 120 hours 70 hours 7 hours 160 hours

Answer 1

You can make this into an equation, i.e. how many lots of 20 make 140
$140 = 20 \times x$
Where x is the number of hours which we don't know
To get just X, we can divide both sides by 20
i.e.
$20 \times x \div 20 = 140 \div 20$
20/20 is 1, so:
$1 \times x = 7$
Therefore X is 7, and so John must work 7 hours to make $140.

Answer 2

Hello there, fellow human being!

The answer is plan simple, 7 hours.
7 times 20 gives you 140.


So, the answer is 7 hours.

Hope this helped!
