200 feet = 0.0378787879 mile

Speed(miles/hours) * Time(hours) = Distance(miles) ------->

As you can see => miles/hours * hours = miles

-----------------------------------------------------------------------------

Therefore :

Distance = 0.037 miles

Speed = 50 miles/hours

Time = ?

Just substitute: 50 * Time = 0.037; ---------------> you get Time = 0.037/50 = 0.00074 hours

one hour is 60 minute: therefore : 60 * 0.00074 = 0.0444 minutes

one minute is 60 sec: 60 * 0.0444 = 2.664 sec ----> 2.664 sec Wiki User

To convert mph to feet per second, always multiply mph by 22/15. As an extension, to convert mph to feet per minute, always multiply mph by 88.

To answer your question, (30) x (22/15) = 44 feet per second   Wiki User

First convert 300 feet to miles : 300 ft x 1 mile/5280 ft = 0.0568 miles

Then calculate time, in hours : 0.0568 miles x 1 hour/30 miles = 0.001894 hours

To get this in minutes, convert : 0.001894 hours x 60 minutes/hour = 0.11363 minutes

To get this in seconds, convert : 0.11363 minutes x 60 seconds/minute = 6.82 seconds   Wiki User

40 minutes

30 miles = 1 hour = 60 minutes

20 miles = 60 x 20/30 = 1200/30 = 40   Wiki User
