Question 925526: [A jet leaves London and flew South. One hour later an Air Force plane left flying 46 mph faster in an effort to catch up to it. After 9 hours the Air Force plane finally caught up. What was the jet's average speed?] Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! x = jet speed (a)
y = air force airplane speed (b)
y = x + 46
---
s = d/t
d = st
---
distance between (a) and (b) when (b) departs:
d = x(1 hour) = x
---
speed of (b) relative to (a)
y - x = 46 mph
y - x = d/t
y - x = x/9
46 = x/9
x = 46*9
---
answer:
x = jet speed = 414 mph
