Sound travels about 343 meters per second. The
function d(t) = 343t gives
the distance d(t) in meters that sound travels in t seconds. How far does sound travel in 8 seconds?
(1 point)
O 343 meters
• 686 meters
O 2,744 meters
• 3,430 meters
To find out how far sound travels in 8 seconds, you can substitute t = 8 into the function d(t) = 343t:
d(8) = 343(8) = 2744 meters
So, sound travels 2744 meters in 8 seconds.
The correct answer is 2744 meters.
