I'm calculating a physics problem and I'm supposed to calculate the height of a building given that:

rock is dropped from the building,

the sound of the rock hitting the ground is heard 4.8s later,

the speed of sound is 350m/s,

and I don't know how do I calculate the time since the rock hit the ground until it reached my ears.

Thank you!
