Jared left the coffee shop traveling 12 mph. Then, 2 hours later, Dakota left traveling the same direction at 18 mph. How long until Dakota catches up with Jared?

Answer 1

Please take a look at the video attached

Answer 2

12X = 18(X-2) = 18X-36

6X = 36

X = 6 hours for Jared. X-2 = 4 hours for Dakota to catch up to Jared

in 6 hours Jared goes 12x6 = 72 miles

in 4 hours Dakota goes 18x4 = 72 miles
