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
