Two planes just took off from Milwaukee wi the first plane is traveling 1.5 times as fast the second plane after traveling in the same direction for 8 hours they are 420 miles apart what is the average speed of each plane

Answer 1

Let's assume the speed of the second plane is "x" miles per hour.
Therefore, the speed of the first plane is 1.5x miles per hour.
After traveling for 8 hours, the first plane has covered a distance of 8 * 1.5x = 12x miles.
At the same time, the second plane has covered a distance of 8x miles.
The distance between the two planes is the difference between the distances covered by the planes, which is 12x - 8x = 4x miles.
According to the problem, the distance between the two planes is 420 miles.
Therefore, 4x = 420.
Dividing both sides of the equation by 4, we get x = 105.
Hence, the speed of the second plane is 105 miles per hour, and the speed of the first plane is 1.5 * 105 = 157.5 miles per hour. Answer: \boxed{105, 157.5}.
