Problema Solution
Two airplanes leave an airport at the same time and travel in opposite directions. One plane travels 63 kilometers per hour faster than the other. If the two planes are 10,470 apart after 6 hours, what is the rate of each plane?
Answer provided by our tutors
let speeds are x and( x+63) km/hr
6x+6(x+63) = 10470
6x+6x+378 = 10470
12x = 10092
x = 841
speeds are 841 and 904 km/hr respectively
