![Given Question:
To Find :
Solution:
Flying against the jet stream a plane Travels 3132 miles in 9 hours. the same plane flying with the jet
stream travels 1.5 times the distance it travelled going against the Jetstream. If the plane Travels 435
miles per hour. what is the speed of the jet stream?
The Speed of the Jetstream
Lets Assume: Sp- Speed of the Plane, Sj = Speed of the Jet
Observation from the question. When plane is against the steam
Given that Sp = Plane speed is 435 miles/hour
We Know that Speed =
→ Sp-Sj=
Speed = Sp-Sj
Distance = 3132 miles
Distance
Time
Here speed is effective speed i.e Sp-Sj, Distance =3132 Miles, Time = 9 hours
3132

3132

= 348
Substituting Sp = 435
→ 435 -Sj =348
→ Sj = 348-435
⇒ -Sj = -87 ⇒ Sj=87 Miles/hour
In Time 9 hours
