Question

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

Answer 1

1 1/2 hours

Explanation:

19m = 1/2h

57m = xh

19 = 1/2

57 = x

19x = 1/2 (57)

19x = 28.5

÷19. ÷19

x = 1 1/2
