Rolande rode a mile in 4 minutes, and Louis in 5 --> Rolande was faster

35.8 mi/hr * (1hr/60min) * (1min/60sec) * (5280ft/1mi) * (12in/1ft) * (2.54cm/1in) * (1m/100cm) = your answer\n\nnotice in each fraction... the top is actually equal to the bottom, but in different units... so you can put whichever one you need on the top or bottom, either way it equals 1... so you just manipulate them based on what you start with and what you need.  i started by converted the hour to seconds, then followed by converting the miles to meters.\n\nI don't remember the other conversions, but you should have them in your text cover and just follow the same method.  Hope this helped.

in a flat stable position it is broadly 120 miles per hour (takes about 10 seconds to get to that).  Head down (max track) you are nearer 200 mph =8-)

I'd say 17000-19000 miles per hour.\n\nIts at a inclined geo-stationary orbit probably.

the speed = distance/time

45 miles / 5 hours = 9mph\n45 miles /3 = 15 mph \n\n15mph - 9mph = 6 mph\nCurrent is 6 mph

...the best way to find out. Use Yahoo! Maps. It'll tell you time + miles :)

Tyler 10 miles in 75 mins => 10m in 1.25 hours => 10/1.25 = 8mph\n\nBrian 4 miles in 30 mins => 4m in 0.5 hours => 4/0.5 = 8mph\n\nAs they both averages 8 miles per hour their rate was the same.

180 miles per hour to go 400 miles is 2.22 hours or about 2 hours and 18 minutes. Stopping for 2 minutes would make the total time 2 hours and 20 minutes.

12 minutes (1/5 of an hour)\n\nDistance (d) = 10 miles\nRate (r) = 50 miles per hour\nTime (t) = Time in hours\nd = r * t\n\nSubstituting:\n10 = 50 * t\n\nt = 10/50\nt = 1/5 hours\n\n1/5 hour * 60 minutes/hour = 12 minutes\n\nThe answer is 12 minutes

By my calculations, if you divide 14.45 by 3, it will get you 4.82 miles per half a mile. You then multiply that by 2 which would get you approximately 9.63. So therefore, you should run about 9.63 miles per hour without any breaks. In a simpler way, 14.45 divided by 1.5.

for the first hour:\nJose travels 5 miles\nMario travels 7 miles\nMelanie travels 9 miles\n\nfor the second hour:\nJose travels 10 miles\nMario travels 14 miles\nMelanie travels 18 miles\n\nJose   (1,5) and (2, 10) are your points\n(10 - 5)/(2-1) = 5 mph\nMario  (1, 7) and (2, 14)\n(14-7)/(2-1) = 7 mph\nMelanie (1,9) and (2, 18)\n(18-9)/(2-1) = 9 mph\n\nANSWERS\nJose\n    5 mph\nMario\n     7 mph\nMelanie\n    9 mph

its right.......... average speed= distance/time\n\nso average speed= 10*3/1\n=>30km/hr

First convert miles to feet:\n\n(90 miles)(5280 ft / 1 mile) = 475,200 feet per hour.\n\nNow that you have a rate, you can find the distance traveled over a period of time:\n\n(475,200 feet)/(1 hour) = (60 feet / ? hours)\n\nSolving for the unknown, you get:\n\n60/475200 = 0.000126262 hours.\n\nNow convert into a more convenient time measurement, like seconds:\n\n(0.000126262 hours)(60 min / 1 hour)(60 sec / 1 min) =\n\n0.45 seconds\n\n--------------\n\nHope this helps

A would take 22 minutes to get to 15 miles and 32 minutes to get to 20 miles. Unfortunately, there's insufficient information to be precise on B's journey. Did he spin off before the start?.. or at which point en route? Guessing it, I would say A arrived at 15 miles and at the 20 miles point first. NB. I have had to make certain assumptions in your question to arrive at this answer (eg I asumed A slows down to 40mph after 4 miles?)
