Answer: The plane had traveled about 264 miles before turning back. The average speed was 230 mph
Step-by-step explanation: 230 - 10 = 220 speed outgoing
230+10 = 240 speed returning
Average speed (220+240)÷2= 460/2 =230 mph (needless to calculate!) Multiplied by total time 2.3 hours = 529 miles total distance.
Traveling the entire distance at 220mph would take about 2.4 hours. Traveling the entire distance at 240mph would take about 2.2 hours, a difference of .20 hours. Cut those times in half:
Traveling at 220mph for 1.2 hours would cover about 264 miles.
Traveling at 240mph for 1.1 hours would cover about 264 miles.
It adds up to 528 miles. The plane can't turn instantly, so figure the turn took the missing mile!

The images of the question are missing, I found a matching question and image online, and it is in the attachments.
Answer:
The scale factor of the triangles from the left to the right is 2
or
The scale factor of the triangles from the right to the left is 1/2
Step-by-step explanation:
From the image, the right triangle on the left has the following dimensions:
Hypotenuse = 10
length of one side = 10
While the right triangle on the right has the following:
Hypotenuse = 20
Length of one side = 20
From the dimensions above it can be seen that the triangle on the right has a dimension of 2 times the triangle on the left:
Left (10) × 2 = right (20)
Therefore the scale factor of the triangles from the left to the right is 2
or
The scale factor of the triangles from the right to the left is 1/2
A/4 + 1.5 = b
