Sound travels about 750 miles per hour. If you stand in a canyon and sound a horn, you will hear an echo.

Respuesta :

Answer:

825 ft

Step-by-step explanation:

750 miles/60/60=0.208333333 miles

sound need to travel to walls and back meaning:

1.5 times .208333333 divided by 2 equals 0.15624999975 miles away

1 - 5280 (miles - feet)

.15624999975 miles in feet = 825 ft
