Elly and sam are jogging. Elly runs from point a to point b in one hour at 2MPH faster than sam if sam takes 1/2 hour more time than elly to go the same distance, find the distance between point a and b.
-------------
Elly DATA:
time = 1 hr ; rate x+2 mph ; distance = x+2 miles
------------------
Sam DATA:
time = 3/2 hr ; rate = x mph ; distance = (3/2)x miles
-------
Equation:
distance = distance
x+2 = (3/2)x)
(1/2)x = 2
x = 4 mph
------
Ans: distance = (3/2)x = (3/2)4 = 6 miles
