Can someone help me with ratios?

Question

I need help with this question

Convert 1500 mph to feet per seconds

Answer 1

One way I remember is that 60mph = 88ft/sec

Therefore 1500 mph = 1500 x 88/60 =2200ft/sec

Answer 2

1 mile = 5280 ft and

1 hr = 3600s

Therefore,

1500m/h = [(1500m) * (5280ft)] /(1 hr * 3600 s)

= 2200 ft/s   is the anwer.

Answer 3

1 mile is 5280 feet

1 second is 3600 seconds

1500 * 5280 / 3600

Answer 4

There are 5280 feet per statute mile.

one hour has 60 minutes.  Each minute has 60 seconds, therefore an hour has 3600 seconds.

If you divide 5280 feet by 3600 you get 1mph equals 1.46667.  Since this value  has an endless value, it is practically useless. The seven at the end will swing your anwser from the real value depending upon how many sixes are used.  So lets just crunch the actual numbers.

Mutiply 1500 by 5280 to get feet per mile.  Then divide this number (7920000) by 3600 and you get 2200 feet per second.

this is twice as fast as a .22 LR high velocity bullet out of a rifle.

Some larger calibers and wildcat rounds went between 3000 to 4000 feet per second.

Answer 5

1 mph = 1.46666667 feet per second

1500 x 1.46666667 = 2200.000005 fps

Answer 6

1500 mph = (1500 x 5280) / 3600 ft / s = 2200 ft / s

Answer 7

2222 feet/second or 2220 feet/second to 3 s.f.
