WILL MARK YOU BRAINLEST IF YOU ANSWER CORRECTLY: Steven and Anna start running from the school. Steven starts 15 seconds before Anna and runs at a rate of 3 feet per second. Anna runs at a rate of 4 feet per second. After how many seconds would Anna catch up with Steven?

After 15 seconds, Anna will catch up with Steven.

Step-by-step explanation: Set up the equation so that their distances will be equal at some time, x.

Distance = speed × time

3x + 15 = 4x . Subtract 3x from both sides

15 = 4x-3x

15 = x  The time is 15 seconds.

At that point their distances will be equal at 60 feet.

3(15) + 15 = 60

4(15) = 60

i got 10.28 but that rounds up to 10.3

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
