Question

Two planes, which are 1730 miles apart, fly toward each other. Their speeds differ by 65mph. If they pass each other in 2 hours, what is the speed of each?

Answer 1

Answer:

400mph and 465 mph

Step-by-step explanation:

let the speed of first plane be x

speed of 2nd plane = x+65

dist travelled by first plane in 2 hrs = 2x

dist travelled by 2nd plane = 2(x+65)= 2x+130

when they meet, the sum of dist travelled by them is 1730

4x + 130 = 1730

4x = 1600

x = 400moh

x+65 = 465 mph
