Notify your teacher and make sure you check your answer. Like a lot.
Use the calculator even. Go online ask google.
But I guess I can help you out with this one. If my math is correct it is.

Answer:
1. 24 km/hour
2. 48 km
Step-by-step explanation:
1 mile = 1.6 km
cyclist = 15 miles/ hour
we want to multiply speed by something that will cancel miles out and leave km. to do this, we want to multiply it by something with miles on the bottom and km on the top.
this is because
miles * km / miles = km as the miles cancel out and km is left in the numerator
thus,
1 mile = 1.6 km
divide both sides by 1.6 km to get 1 on a side
1 mile / 1.6 km = 1
alternatively, divide both sides by 1 mile to get 1 on a side
1.6 km / 1 mile = 1
since we want miles on the bottom, we choose the second option
cyclist = 15 miles / hour = 15 miles/hour * 1 = 15 miles/hour * 1.6km / 1 mile = 24 km /hour
24 km/hr for 2 hours = 24 km/hr * 2 hours = 24 * 2 km = 48 km
So I think you’re looking for an outlier not an outliner. An outlier is a piece of data that doesn’t match the trend, like the misfit that doesn’t fit with the rest. For example if I had measurements of 1,2,4,84,3 then 84 would be the outlier. Hope this helps!
The mean of a data us the addition of all numbers in the data set and then dividing them by the number of values in a set.
<h3>What is a mean?</h3>
Your information is incomplete. Therefore, an overview will be given. It should be noted that a mean simply means the average of a set of numbers that are given.
For example, if we have the following numbers:
3, 9, 4, 1, and 3. The mean will be:
= (3 + 9 + 4 + 1 + 3)/5
= 4
The mean absolute deviation is the average distance between the data points and the mean.
