Rita and sita start jogging at the same point but in opposite directions. If the rate of one jogger is 2 mph faster than the other. After 3 hours, they are 30 miles apart, what is the rate of the faster jogger?

Answer 1

[r + (r - 2)] * 3 = 30

solve for r

Answer 2

1st jogger: X mi/h.
2nd jogger: (x+2) mi/h.

d2 - d1 = 30 miles.
3(x+2) - (-3x) = 30,
3x+6 + 3x = 30,
X = ?
x+2 = __mi/h. = speed of 2nd jogger.
