Ben strikes a large metal sheet with a hammer.

Ava starts a stopwatch when she sees the hammer strike the metal sheet.

Ava stops the stopwatch when she hears the bang.

A diagram showing two students, Ben and Ava, standing 170 meters apart on a school playing field. Ben is holding a hammer next to a large metal sheet. Ava is holding a stopwatch.

The distance between Ben and Ava is 170 m.

Ava's reaction time is 0.22 s.

The speed of sound in air is 340 m/s.

Calculate Ava's reaction time as a percentage of the time sound takes to travel from Ben to Ava.
