Question 831566: A jet airplane takes 45 min to fly 495 miles from Dallas to Kansas City. Suppose another jet travels at the same rate from new York to los Angeles, a distance of 2,786 miles. How long will it take? Using proportions and tound to nearest minute.
Answer by hovuquocan1997(83)   (Show Source):
You can put this solution on YOUR website! It says suppose that the second jet has the same speed at the first one, the formula for speed is time/distance, in this case both speed equal, so we have the equation:
45/495 = x/2768 (x is the time that we need to find)
x = (2768*45)/495
x = 251.63636363636363636363...........
And because the question tells you to round (I suppose you made a mistake cuz I don't know what tound means hehe) to the nearest minute, so .........
TA-DAH
252 minutes is your answer :D
