Answer:
B) 13
Step-by-step explanation:
Answer:
A y=5x
Step-by-step explanation:
We need to find the slope
Given the two point (0,0) and (2,10)
slope = m = (y2-y1)/(x2-x1)
=(10-0)/(2-0)
= 10/2
=5
The slope is 5
We know the y intercept ( where it crosses the y axis) is at 0
The equation of a line in slope intercept form is y= mx+b
y = 5x+0
y=5x
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
