I think you did the question wrong
Hi
60 miles in 1.5 hour mean speed of 60/1.5 = 40
If speed is reduce of 5, then she drive at 35 mph.
so 35*3 = 105 miles in 3 hours.
The median {Q2} is 10
Q1 is 7+7/2 which is 7
Q3 is 15+12/2 which is 13.5
Well, first Geometric Mean is a<span> special type of average where we multiply the numbers together and then take a square root (for two numbers), cube root (for three numbers) etc.
So, the first step in solving this problem is taking 2 and 3 and multiplying them
(2x3=6).
Now, for the second step, we will cube it. Since there are 2 numbers, we are going to use the 2nd root ( 2</span>√6)
This will give us: 4.89897948557 or 5 if you would round it. This would be the Geometric Mean.
