Answer:
Her usual rate is 0.8333 miles per hour.
Step-by-step explanation:
The velocity formula is given by:
In which d is the distance and t is the time.
She completed the first half of the walk 1 mi/h faster than usual
Her usual rate is v. 1mph faster is v + 1.
The second half of the walk 2 mi/h slower than the first half.
The first half is v + 1.
2mph slower is v + 1 - 2 = v - 1. Then
Total rate:
7.2 hours, and 6 miles. So
One half is v+1 and the other is v - 1. This is why each is multiplied by 0.5.
Her usual rate is 0.8333 miles per hour.
Answer:
Step-by-step explanation:
The equation of a circle is where
is the center of the circle and
is the radius of the circle.
Given that and it passes
, their distance between each other must the radius of the circle, so we can use the distance formula to find the radius:
Therefore, if the length of the radius is units, then
, making the final equation of the circle
