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
