Answer:
15 cm
Step-by-step explanation:
Circumference of circle= 2πr, where r us the radius of the circle.
Given that the circumference of circle is 60πcm,
60π= 2πr
Divide by 2 on both sides,
15π= πr
Divide by π on both sides,
15= r
Thus, radius of circle= 15cm.
It took both 2.5 hours to be 110 miles apart
Speed is the ratio of distance travelled to time taken. Speed is given by:
Speed = distance / time
Since both steamers is travelling at 22 mph. therefore they cover the same distance at the same time. For them to be 110 miles apart, they need to each have covered 55 miles in the opposite direction
22 = 55/time
time = 2.5 hours
Therefore after 2.5 hours they would have covered 55 miles each therefore being 110 miles apart.

Answer:
see explanation
Step-by-step explanation:
given the endpoints of a line segment
(x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[
(x₁ + x₂),
(y₁ + y₂) ]
For example
consider the endpoints (4, 2) and (6, - 4)
midpoint = [
(4 + 6),
(2 - 4)] = (5, - 1)
