Question

Ellie and Justin are 22 miles apart from each other on a path. Ellie walks at a constant speed of 4 miles per hour, Justin walks at a constant speed of 1.5 miles per hour. How long does it take until Ellie and Justin meet?

Answer 1

Ellie: s = 4 m/h

Justin: s = 1.5m/h

D = r • t

D is distance apart

r is rate/speed

t is time

r = 4 + 1.5 = 5.5 mph

d = 22m

Find t?

22 = 4•t

22/4 = t

t = 5.5 h

It will take 5.5 hours to meet up.

Answer 2

It would take 55 hours until Ellie and Justin meet. This is found in the equation y=55h aka y=55x.

Answer: y=55h
