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?

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,

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

Step-by-step explanation:

Let the length of the road be x miles.

Hence length of the road = 1.5 miles.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
