You need to build an equation according to the units.
X hour * 65 miles/hour = 220 miles
You can see that when you multiply "hour" by "miles/hour" the "hour" cancels out and you're left with just miles.
So, now we have the equation, just solve like you would any other equation.
Time = Distance/Speed.
2 hours, 45 minutes
Divide distance by speed; 21/220 = .0955 hours = 5.73 minutes
440/70 = 220/35 = 44/7 = 6 and 2/7 hours
It's about 220 miles which would take a little less than 4 hours (going 60 MPH) if you don't hit traffic.
How long dose it take to go 20 miles at 90 mph
what do ya think mph stands for... miles per hour. it will take one hour to drive 60 miles at 60 mph.
It would take 12 minutes to drive 20 miles at 100 mph.
It will take 20 min to go 20 miles at 60 mph.
The jet is traveling 440 miles divided by 2, or 220 mph. In 11 hours, it would fly 11 hours times 220 mph. 11 hours x 220 mph = 2420 miles The rate of speed is 220 mph and the distance the jet could fly is 2420 miles.
At 35 MPH you are moving 51.33 feet per second. You will therefore travel 220 feet in 4.28 seconds.
@ 250 mph
