Question

Two ships leaving the same marina at the same time are 3.2 miles apart after sailing 2.5 hours. if they continue at the same rate and direction, how far apart will they be 2 hours later?

Answer 1

Hey there!

2 hours + 2 hours = 4 hours

2.5 hours : 3.2
4 hours : x
$2.5x = 3.2 \times 4 \\ 2.5x = 12.8 \\ x = 5.12$

Answer : 5.12 miles

Hope this helps. - M
