Anna begins jogging at a steady 3 m/sec down the middle of lane one of a straight track. Elsa starts even with her in the center of lane two but moves at 5 m/sec. At the instant they begin, Olaf is located 45 meters down the track in lane four, and is heading towards them in his lane at 6 m/sec. After how many seconds will the runners lie in a straight line?

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
