Most bats find their way around by making high-frequency sounds, which reflect back to them off surrounding objects. A bat can emit a sound wave that travels at a speed of 343 m/s. Speed, s, can be represented by the formula, s= d/t, where d is distance, in metres, and t is the time, in seconds.
A) write an equation that can be used to determine how many metres a bat is away from an object and back.
B) how far is the bar from the object?
C) if a bat is 30 m from your house, how many seconds will it take for the bat to emit and receive a sound wave? Round your answer to the nearest hundredth of a second.
