Answer: The distance around the lot is given by
Step-by-step explanation:
Since we have given that
Length of rectangular lot is given by
Width of rectangular lot is given by
We need to find the distance around the lot.
As we know the formula for "Perimeter of rectangle":
Hence, the distance around the lot is given by
Given :
Peter velocity , P = 30 mph .
Mitchell velocity , M = 40 mph .
Mitchell leaves 15 min later .
To Find :
If they drive along the same route how long will it take Mitchell to catch Peter.
Solution :
Distance covered by Peter in 15 min .
Let , time taken is x .
So , distance covered b them is equal :
Therefore , time taken by them is 45 minutes .
Hence , this is the required solution .
Suppose that a>b>1, then
and
Therefore, since 2<3<7,
Choose an arbitrary x>1. You have that a takes the greatest values at x, c takes the smallest value at x. Thus,
a>b>c and
Answer: correct option is B.
