To reach a stranded family, they travel 7 mi against the current and return 7 mi with the current in a total time of 1§ hr. What is the speed of the current?

- 30

Step-by-step explanation:

The 2 numbers are x and 2x and thir product is 1800, that is

x × 2x = 1800

2x² = 1800 ( divide both sides by 2 )

x² = 900 ( take the square root of both sides )

x = ± = ± 30

The 2 numbers are 30 and - 30 with - 30 being the lesser number
