Question

Gerry just returned from a cross-country trip. The trip was 3,000 miles from his home, and his total time in the airplane for the round trip was 11 hours. If the plane was flying at a rate of 550 miles per hour, what was the speed of the jet stream?

Answer 1

The speed of the jet stream is 4.55 miles per hour

Step-by-step explanation:

Distance of one way trip= 3000 miles

The total distance of the round trip= 6000 miles

Total time = 11 hrs

Speed of the plane = 550 miles per hr

Speed = distance/time

= 6000/11

= 545.45 miles per hour

Speed of the plane = 545.45 + speed of the jet stream

550 = 545.45 + speed of jet stream

Speed of jet stream = 4.55 miles per hour

The speed of the jet stream is 4.55 miles per hour
