Attached Table.
The median is the "middle" value from all the numbers arranged from least to greatest.
Looking at the table, we need to arrange the numbers (first week numbers) from least to greatest.
-31, -29, -9, -8, 3, 4, 6
There are 7 numbers and the middle number is the 4th one, which is -8
The median is -8°F
Complete question:
Anty was riding his bike to school at a speed of 12 mph. When he was <u>half </u>of the way there, he got a flat tire. His mother drove him the rest of the way at a speed of 48 mph. What was his average speed?
Answer:
His average speed is 19.2 mph
Step-by-step explanation:
Given;
speed of Anty to school half of the way, v₁ = 12 mph
speed of Anty when his mother drove him half of the way, v₂ = 48 mph
The average speed of Anty is calculated as;
The value of the average speed is closer to 12 mph than 48 mph because Anty spent more time moving at 12 mph than at 48 mph.
Let the equal distance travel at each speed = 96 miles
Time taken at 12 mph =
Time taken at 12 mph =
Average speed =
Also, you can assume any other equal distance traveled at each speed, the average speed will still be 19.2 mph.
<u>Check:</u> let the equal distance traveled at each speed = 480 miles
Time taken at 12 mph = 480/12 = 40 hours
Time taken at 48 mph = 480/ 48 = 10 hours
Average speed = (480 + 480) / (40 + 10)
= 19.2 mph
