OK, it just came to me. Time rising= altitude/veloictyrising=202/1.1= XXXseconds. during that time, it travels this horizontal distance: distance=xxxxseconds*2.7m/s Then add to that, the distance when at constant altitude distance= 10.3*2.7m/s

The time is the distance divided by the velocity. The total time is the time at 88km/h + the time at the unknown speed v. Half the distance is run at each speed: 0.8/88 + 0.8/v = 1.6/67 .009091 + 0.8/v = .02388 .8/v = 0.01365 v = 58.6 km/h

I suppose you could work the 2-4 combinations out and memorize them; however, it's relatively easy to do one. For example, for the rate = k(x)^1(y)^2 for a third order reaction, you have k = rate/(x)^1(y)^2 = rate is M/t where M is molar and t is time. Tben k = (M/t)/(M)(M)2 k...

consider the mug: F=ma you know F, you know the time of force (time=distance/velocitycloth), so Force*time=massmug*velocitymug from that,you caculate the averagevelocity of the mug (1/2 velocityfinalmug), then distance=avgvelocity*time

Science
The distance will rise as time increases, at an increasng rate (slope). The curve is called an upward parabola.

The speed of light is, for all practical purposes, 3 x 10^8 meters/second. Distance = rate x time.

do distance=rate*time for each leg, then add the distances. Change min to hour by dividing by 60.

You cant trust the average always. I assume you are using a rate equation, amount=rate*time Consider in 28 hours, shelby can paint 7, and Zoe can paint 4. So the combined rate = (7+4 rooms)/28 hrs= 11/28 rooms/hr Now the time to paint one room amount= rate*time time= amount/...

Physics
force= mass*acceleration average velocity= distance/time final velocity= 2*distance/time acceleration= (finalvelocity-0)/time = 2*distance/time^2 Or you can do it this way: Vf^2=Vi^2 + 2 a d where a is Force/mass

They both travel the same distance, in the same time. truck: distance=10t car: distance=1/2 2 t^2 10t=t^2 10=t so time is ten seconds. distance=10*t velocitycar=2*t=20m/s

Math
rate of 1st tap = 1/4 rate of 2nd tap = 1/6 rate of both taps = 1/4 + 1/6 = 5/12 time at combined rate = 1/(5/12) = 12/5 or 2.4 minutes

Well The person typing is going at a rate of 90 mintutes per rate and is getting payed 2$ per minute. Is 10 dollars for 1800 words a better pay than the rate of the time taken???

Math
Distance = Rate * Time or D = RT for Pete : D = 9x for Jan : D = 18(1.5) so 9x + 18(1.5) = 42 solve for x (I got 1 hour, 40 minutes)
