Question

A crew has paved 3/4 of a mile of road . If they have completed 50% of the work how long is the road they are paving?

Answer 1

Step-by-step explanation:

Let the length of the road be x miles.

$\therefore \: 50\% of \: x = \frac{3}{4} \\ \\ \therefore \: \frac{50}{100} \times x = \frac{3}{4} \\ \\ \therefore \: x = \frac{3}{4} \times \frac{100}{50} \\ \\ \therefore \: x = \frac{3}{4} \times 2 \\ \\ \therefore \: x = 1.5$

Hence length of the road = 1.5 miles.

Answer 2

The total length of the road which is needed to be paved is 1.5 miles.

Given information:

A crew has paved 3/4 of a mile of road.

The completion of the work by the crew is 50%.

So, the crew has completed half the work or has paved the half-length of the road.

The half-length of the road will be 3/4 of a mile or 0.75 miles.

So, the total length of the road can be calculated as,

$l=2\times 0.75\\l=1.5\rm\; miles$

Therefore, the total length of the road which is needed to be paved is 1.5 miles.
