Question

When the temperature is 68°F, the speed of sound in air is approximately 343 meters per second. Approximately how many kilometers does sound travel in five seconds?
I will give 10 points. Please explain each step you did to solve and find the answer please! Thank you to those who help me!

Answer 1

If the speed of sound is 343 m/s, multiply that by 5 for five seconds and you get 1715 meters. Divide this by 1000 to get kilometers, and you have 1.715 kilometers

Answer 2

Well,

We have our initial unit of speed: 343 m/s.

We want to find how many kilometers sound will travel when the air is at 68 degrees in five seconds.

Step 1: Multiply 343 by five. (1 sec. to 5 secs.)
343 * 5 = 1715

Step 2: Divide 1715 by 1000. (1 m. to 0.001 km)
1715/1000 = 1.715 km/5 secs.

At a temperature of 68°, sound will travel 1.715 km in 5 seconds.
