A bat, flying toward the east at 2.0m/s, emits a shriek that is reflected back to it from a wall?

that is 20.0 m in front of the bat at the instant the shriek is emitted. Sound travels at 340 m/s in the air. How many milliseconds after emitting the

that is 20.0 m in front of the bat at the instant the shriek is emitted. Sound travels at 340 m/s in the air. How many milliseconds after emitting the shriek does the bat hear the reflected echo from the wall?

Please help! I'm having trouble combining the components of the question into a single answer that matches the correct 117 ms answer.

or:The distance is 40 m because it is reflected back. t = distance/speed t = 40 m/340 m/s = 0.1176 s then convert seconds to milliseconds by multiplying by 1000 ms answer= 117.6 ms
