Question 339954
There are 3600 in one hour.

So, 10/3600 = (1/360) of an hour.

D = rt

D = distance

r = rate in mph

t = time (in hours)

700 = (1/360)r

700 divided by (1/360) = r

252,000 = r

The miles per hour is 252,000.

We now muct convert 252,000 feet per hour to miles per hour.

252000ft per hour / 5280ft per mile = 47.72727272... miles per hour

Understand?
