Step-by-step explanation:
The easiest approach is to realise that one hour is 3 times longer than
20
minutes. The longer the time, the more they will pave.

of a mile, in 20 minutes, how much in 60 minutes?#
They will pave 3 times more.

You could also use the 'unitary method' where you find out how much they pave in ONE minute (divide by
20
) and them multiply by
60
to find how much in one hour.
Look at what happens:

$5000 × 0.048×2= $480
Answer: $480
You would input 10 as m into the equation
t= 0.05(10) +60
t=0.5+60
t=60.5
We can say that ‘0’ is also a rational number since it can represent it in many forms of 0/1, 0/2, 0/3, etc. So yea it is hope this helped!
