A jet left the airport flying north five hours before a passenger plane. The passenger plane flew in the opposite direction going 260 km/h faster than the jet for htree hoiurs after which time the planes were 2650 km apart. What was the jet's speed?
jet speed = x
passenger plane speed = 260 + x
Jet had 5 hr headstart distance = 5x + 3 more hours = 8x
then the passenger jet took off and flew 3 hours = 3 (260+x)
total distance = 2650 km
8x +3 ( 260+x) = 2650 solve for 'x'
