Answer:

174 seconds or 2 minutes, 54 seconds

Step-by-step explanation:

you can set up a system up equations to solve this problem:

Keith:    y = 1x + 200

Erica:    y = -1x + 548

if you graph the above lines, their point of intersection is the solution

in this case, after 174 seconds both balloons will be 374 feet above the ground
