Question

A submarine travels 19 miles in 1/2 hour. Write an equation to find out how long it would take the submarine to travel 57 miles at the same rate. Then find the time.

Answer 1

I put the wrong answer don’t mind me

Answer 2

1.5 hours

Explanation:

We can write a ratio to solve

19 miles 57 miles

-------------- = --------------

.5 hours x hours

Using cross products

19x = 57*.5

19x =28.5

Divide each side by 19

19x/19 = 28.5/19

x =1.5
