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?

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

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

answer: this is not a question
