Since the given coordinates are already in order,
then and two consecutive distances between the coordinates will give length and breadth,
Using distance formula,
(we'll not consider the negative value since distances can't be negative)
Applying this again on 2nd and 3rd coordinates,
(we'll not consider the negative value since distances can't be negative)
Since length's always gotta be greater than bredth
therefore,
the difference will be 5-4= 1 units
Hence width is 1 unit shorter than length.
Note: Unit used is "unit/s"

Given Information:
Distance = 160 miles
Required Information:
Rate = r = ?
Answer:
Rate = r = 20 mph
Step-by-step explanation:
Recall that the rate is given by
Rate = distance/time
It is given that the same trip would have taken 2 hours longer if he had decreased his speed by 4 mph.
Mathematically,
Simplify the equation
Now we are left with a quadratic equation.
We may solve the quadratic equation using the factorization method
So,
OR
Since rate cannot be negative, discard the negative value of r
Therefore, the rate is
