Kelka's family drove to Long Island. They drove 1 1/2 hours to get there. The return trip only took 3/4 of the time of the origi

Anton [14]

The trip was 6 hours long.

Step-by-step explanation:

Given,

The time to go to the island = 1 $\frac{1}{2}$ hours.

The return trip took 3/4 of the time of the original trip.

To find the time of the trip.

Let,

The time of the original trip is x hours.

The time for returning = $\frac{3x}{4}$

According to the problem,

1 $\frac{1}{2}$ + $\frac{3x}{4}$ = x

or, x - $\frac{3x}{4}$ = $\frac{3}{2}$

or, $\frac{x}{4}$ = $\frac{3}{2}$

or, x = $\frac{3}{2}$ ×4 = 6 hours

Hence,

The trip was 6 hours long.
