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!

Smith elementary school score is x -30.
A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
Given:
Smith elementary school scored 30 less points in their track meet than Jones elementary school.
If Jones elementary school scored x points.
So, Smith elementary school score expression is x -30.
Hence, the expression is x-30.
