The answer to this question should be 145
First plug 32 in for x 14(32)t=46
Now solve for t
448t=46
T=46/448 which can be simplified to 23/224

The equation has to (or be transformed to) contain one object in the left side and the other object at the right side multiplied by a constant, without an independent term.
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.
