I'm going to use minutes instead of hours.\nWe know that on the first trip, D = 120S (D=distance, S=Speed of first trip).\nWe know that one the second trip, D = 90(S+6).\n\nTherefore 120S = 90S + 540, or 30S = 540, and S = 18kph.\nTherefore the distance is 36 kilometers.\nChecking, 24(1.5) for the second trip also = 36.

try: \n\nF=m*a =>     0.3*M*g = M*a    =>    a=0.3*g\n\na*t = 60 miles/hr   =>    \nt = 60miles/hr / (0.3 g) = (60 miles per hour) / (0.3 * 9.8 ((m / s) / s)) = 9.12 seconds\n\ndistance\nD=1/2*a*t^2 = ((0.5 * 0.3 * 9.8 * (m / s)) / s) * ((9.12 sec)^2) = 122.266368 meters

18 blocks / 9 min = 3 blocks / x min\ncross multiplying yields 3/2 for x, so we have:\n3 blocks / (3/2 minute) \nSince 3 blocks = 1 mile, and we want miles per hour:\n(1 mile / (3/2 minute)) * (60 minutes / 1 hour) = 40 mph

Convert km to meters to centimeters to inches.\n\n1 km = 1000 meters\n1 meter = 100 centimeters\n2.54 centimeter = 1 inches\n\nthus there are 73 * 1000 * 100 / 2.54 inches

Up Is above, down is below. A pint is a pound the world around. 1" = 1 mile and my finger is 4 inches. Left is Port. No, wait a minute port is a wine or was it as cheese. watch for falling rocks. set a good example for your little brother. Look both ways before crossing the street. If they come for you, you don't know me. Always wear clean underwear. Help me, I am very confused. What was the question again? I forgot.

Average adult step is app. 35-40 cm. \n\nMultiply by 10000, it makes 350000 - 400000 cm which is 3500 - 4000 meters. \n\nThat makes  3,5 to 4 kilometers. \n\n1 mile is 1,609344 km. \n\nSo it's an approximate of 2,17 to 2,48 miles.

Let s = speed of the boat\n\n60 / (s - 10) = 140 / (s + 10)\n140(s - 10) = 60(s + 10)\n140s - 1400 = 60s + 600\n80s - 1400 = 600\n80s = 2000\ns = 2000 / 80\ns = 25\n\ncheck:\n60 miles at 15 mph = 4 hours\n140 miles at 35 mph = 4 hours\n\nThe answer is 25 mph.

A: 56 mph x 1.5 hours = 84 miles\n\n\nB: Distance = 100 total miles - 84 miles = 16 miles.\nTime = 30 minutes = 0.5 hours.\n\nAverage speed = 16 miles / 0.5 hours = 32 miles per hour.\n\n\nC: Total trip miles = 100 miles\nTotal time = 2 hours (1 hour 30 minutes for first leg, 30 minutes for final leg)\n\nAverage speed = 100 miles / 2 hours = 50 miles per hour.

You just need to look at the prefixes to these words. Kilometer is kilo-meter. Kilo means one thousand. Thus, a kilometer is a thousand meters. So how many "thousand-meters" is 400 meters? Les than one, because 400 is less than 1000. And exactly it is 400/1000 = .4km.\n\nThe same goes for hectometers. Hecto means one hundred. So, how many "hundred-meters" is 400 meters? Clearly it's 4. 400/100 = 4hm.\n\nTa-da!

I assume you mean kilometer?\n\n1 kilogram  == 2.2046 pounds\n\n1 kilometer == 3280.84 ft \n1 kilometer == 2/3 of a metric mile\n1 kimometer == .625 (5280 feet statute mile)\n\n\nSome online conversion sites.

Ok. 45 minutes is equal to 3/4 of an hour. To find the distance Travis has travelled at that point in time, you will need to multiply 55 (his rate) by 3/4. That is equal to 41.25 miles. Now we need to find if Roy will ever catch up to him. We are trying to find when their distances are equal, so time can be our variable. \n\n41.25 + 55t = 65 t \n41.25 = 10t\nt = 4.125 hours\nNow, if we plug that in to 41.25 + 55 t and it is greater than 450, then Roy can't reach Travis before Travis reaches Pecos. \n41.25 + 55 (4.125) = 268.125\n4.125 hours after Roy leaves Dallas, he will catch up to Travis 268.125 miles from Dallas.
