Answer:
1687.5 miles
Step-by-step explanation:
Given: A jet plane traveling at 450 mph overtakes a propeller plane traveling at 250 mph that had a 3-hour head start.
To Find: How far from the starting point are the planes
Solution:
Speed of jet plane =
speed of Propeller plane =
Distance travelled by propeller plane in 3 hours head start =
= =
Distance to be travelled by jet plane to overtake propeller plane =
Relative speed of both planes =
Time taken by jet plane to overtake propeller plane =
total distance travelled by plane =
planes are far from starting point.
