Fireworks can go up to 1000 feet in around 3 seconds. what is its average vertical speed in feet per second and miles per hour?

Distance Covered, D=1000 feet

Time taken, T=3 seconds

Therefore, Speed in feet per second is,

Now, to calculate the speed in miles per hour all that we have to do is to know the relationship between seconds and hour and feet and mile.

mile

We also know that there are 3600 seconds in 1 hour. Thus,

if in 1 second fireworks go 0.0631306818 mile

then in 3600 seconds (or 1 hour) they go miles

Therefore, the speed of the fireworks in miles per hour is:

222.27 miles per hour.
