40 calls in 20 hours=__calls in 10 hours

I have my answer my mom said its right my dad said its wrong what do u smart people think

Answer 1

Answer:  20 calls

Explanation: This is because since 40 is half of 20, you would need to divide by 2 to get 10. If you convert the division to multiplication, 10 * 2 = 20. So, the answer would be 20 calls.
