Answer:
484 miles a day
Step-by-step explanation:
1,942 - 490 = 1,452
1,452 ÷ 3 = 484 miles
The girl's speed is 1380mm/sec * 1cm/10mm * 60sec/minute (since 1cm=10mm and 60 sec=1 minute)= 1380*60cm/10min= 1380*6cm/min
=8280 cm/min. For the turtle, we have 1584 m/hr * 1 hr / 60 min * 100 cm /1m (we have to make sure that they cross out, so e.g. for the hour we multiply it by 1 hr/60 min since the original hour is on the bottom)= 158,400cm/60min
=15840cm/6min
= 2640 cm/min
Since the girl is 8280 cm/min and the turtle is 2640 cm/min, we divide them to get 8280/2640= around 3.136 cm/min
100-21= 79
711=79%
711/1=79/100
711/79=9
9x100=900
the trip was 900 miles all together. you can check if your answer is right by multiplying 900 by 0.79. If it comes out to 711, you are right.

How to Find the Mean
Add up all data values to get the sum
Count the number of values in your data set
Divide the sum by the count
Calculate the mean of 2,3,4,5,8,8,12
Step 1: Add all the numbers together, to find the sum
2 + 3 + 4 + 5 + 8 + 8 + 12 = 42
Step 2: Count the number of values in your data set
There are 7 numbers
Step 3: Divide the sum by the count
42 ÷ 7 = 6
So the mean is 6
