A diver uses a sonar device to determine the distance to her diving partner. The device sends a sound wave and records the time it takes for the wave to reach the diving partner and return to the device.
Suppose the wave travels at a rate of about 4800 feet per second. (Distance = Rate x Time)
a) The wave returns 0.2 seconds after it was sent. How far did the wave travel?
b) How far away is the diving partner?

40% off the regular price is the correct answer.

step-by-step explanation:

bn,mn,n.vn.

step-by-step explanation:

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!

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .
