Question:
Plane 1 leaves city a at 7 am and flies at a speed of 250 mph in a straight line towards city b, located 1000 miles north of city a. plane 2 leaves city c located 300 miles east and 400 miles north of city a at 7: 30 am and flies west at a speed v mph. the planes fly at the same altitude. for which value of v do they collide ?
Answers
v=142.85 mph
Explanation:
Given
Distance between two cities is 1000 miles
Speed of plane 1 id 250 mph
Plane 1 leaves at 7 am and Plane 2 leaves at 7:30 am
They will collide if plane 2 travels 300 miles and Plane 1 travels 400 miles in t and t+0.5 hr respectively
Time taken by plane 2
[tex]t=\frac{300}{v}[/tex]----1
time taken by plane 1 to travel 400 miles
[tex]t+0.5=\frac{400}{250}[/tex]-----2
substitute value of t in 2
[tex]\frac{300}{v}+0.5=\frac{400}{250}[/tex]
[tex]\frac{300}{v}=2.1[/tex]
[tex]v=\frac{300}{2.1}=142.85 mph[/tex]
