Two jets leave Ontario at the same time one flying East at a speed of 20 km greater than the other which is flying West. After4 hours the planes are 6000 km apart. Find their speeds?

Suppose the one flying West goes at x kph. The other is going at (x + 20) kph.
They get further apart by: x + x + 20 = 2x + 20 kph.
Hence 4*(2x + 20) = 6000
So 2x + 20 = 1500
2x = 1480
x = 740
So the speeds are 740 and 760 kph.

Do planes only fly clockwise around the world?
Aircraft fly in the direction of their destination regardless which way around the world that may be. That's a trick question. To an observer standing at the North Pole, a plane flying east to west is going clockwise. To an observer standing at the South Pole, a plane flying west to east is going clockwise. And, of course, some planes fly over the poles. But if you only consider planes that are flying east/west, they are going both clockwise and counterclockwise, depending on which direction you are viewing them from.
If a plain is flying 650 mph traveling at 3575 miles what is the flying time of the plain?
