A pair of kids and a pair of adults decided to compete in a three-legged race. The kids got to start 15 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?

A.) 25 meters; 7 seconds
B.) 5 meters; 20 seconds
C.) 7 meters; 25 seconds
D.) 20 meters; 5 seconds

The answer would be D. 20 Meters; 5 Seconds.

5 Seconds into the race, the adults and children are neck and neck, however the adults go 4x faster than the children.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

pretty sure 750 each month!
