Sound travels about 750 miles per hour. If you stand in a canyon and sound a horn, you will hear an echo.
1 answer:
Answer:
The sound takes time to go to a point and reflect back to your position.
It means the sound went twice a distance.
=> Suppose it takes about 0.5 seconds to hear the echo, the canyon wall would be [750 x (0.5/3600)]/2 = 0.052 miles
=> Suppose it takes about n seconds to hear the echo, the canyon wall would be [750 x (n/3600)]/2 miles

Answer:10
Step-by-step explanation:
Use the distance formula to determine the distance between two points.
the answer will be 10
1.50 x + 2 x = 10.50
add similar elements:
1.50 x + 2 x = 3.5 x
3.5 x = 10.50
x = 10.50 / 3.5
x = 3 magazines.
