Generalizing in order to solve symbolically,
Let d = 3000 miles between locations
let x = time in hours until subjects meet
p = speed of Sol, 200 mph
r = speed of Robert, 400 mph
notice p
During unknown time x, Sol and Robert move their distances, and the sum of their distances is d.
_____The Answer in Symbolic Form.
Just substitute the given numeric values to find x.
