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
Just under 15 minutes.
It's about 220 miles which would take a little less than 4 hours (going 60 MPH) if you don't hit traffic.
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.
Two hours at 60 mph
At 35 MPH you are moving 51.33 feet per second. You will therefore travel 220 feet in 4.28 seconds.
@ 250 mph
