A pair of kids and a pair of adults decided to compete in a three-legged race. The kids got to start 36 meters ahead of the adults, since they had shorter legs. When they were told to start, the kids hobbled forward at a rate of 1 meter per second, and the adults hobbled after them at a rate of 4 meters per second. Soon they were side-by-side. How far did the adults go? How long did that take?
+2668 Write as an equation: \(36+x = 4x\)
Subtract \(x\) from both sides:
\(36 = 3x\)
Divide each side by \(3\)
This means that after \(\color{brown}\boxed{12}\) seconds, both the adults and the children ran \(\color{brown}\boxed{48}\) meters.
