A plane will travel 840 miles if it flies at 210mph for 4 hours.
The plane would have gone 200 mile in one hour.
65*3 = 195 miles.
2 hours. If the train is one mile long and going 1 mile per hour through a mile long tunnel, in one hour the train would be completely inside the tunnel, since they are the same length and the train is only going one full tunnel length(mile) per hour. It would then take another whole hour for the end of the train to leave the tunnel, bringing the train completely out of the tunnel.
300 miles per hour ==> 1 mile every 12 seconds
1 mile = 8 furlongs 1 fortnight = 14 days 1 day = 24 hours 75 miles/hour * 24 hours/day * 14 days/fortnight / 8 furlongs/mile = 3150 furlongs/fortnight
A private plane leaves an airport and flies due east at 192 miles per hour. Two hours later, a jet leaves the same airport and flies due east at 960 miles per hour. How far will the private plane fly before it is passed by the jet?
The plane would have gone 200 mile in one hour.
9 hours
100.000/60 = 1.667 hours.
1 mile per hour.
= 240/6 mile/hour = 40 miles/hour
15 minutes, because 4 miles in an hour is 1/4 hours per mile
approximately 5.5 miles/hour ============= Solution Method: ----------------- There are 60 minutes in 1 hour. We often say there are 60 minutes per hour. We express this relationship mathematically as: 60 min/hr To convert miles/min to miles/hr, do the following: 1 mile/11 min * 60 min/1 hr = 60 / 11 = ~5.45 miles/hr (average speed) * Note: minutes cancel in the numerator & denominator). ----------------- Original answer: 60/11 = 5.45 recurring (that is, 5.45454...) miles per hour. Therefore, running a mile in 11 minutes corresponds to 5.45 recurring miles per hour.
At 60 miles per hour
The reciprocal of mph is 1/mph, or the reciprocal of miles/hour is hours/mile. For instance, if you were going 20 miles per hour, you would also be going 1/20 hours per mile, or 3 minutes per mile.
(200 mile)/(45 mile/hr) = 4.4444 hours = 4 hours & 26.6667 minutes
1 / 42 mph = 0.02381 hours per mile0.02381 hours per mile x 3600 sec. per hour = 85.7143 seconds per mile.
