Answer: 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
