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!
Step-by-step explanation:
To find the mean absolute deviation of the data, start by finding the mean of the data set.
Find the sum of the data values, and divide the sum by the number of data values.
Find the absolute value of the difference between each data value and the mean: |data value – mean|.
Find the sum of the absolute values of the differences.
Divide the sum of the absolute values of the differences by the number of data values.
Answer:
Step-by-step explanation:
Only one answer will do for this question and that is 1.
y/x = 5/5 = 1
y/x = 6/6 = 1
y/x = 1/1 = 1
The one you have to be careful with is when x = 0 y = 0. You can't solve this by using y/x because 0/0 is undefined at this point.
Basically ur just looking for the LCM (lowest common multiple) of all of these numbers.
3,7,12,14....lowest number that all 4 of these numbers go into evenly is 84.
so they will ring together next in 84 minutes (1 hr 24 minutes) making it 5:24 a.m.
