Umm, I don't feel like typing (too lazy and tired to do that lol) so I will attach a written file.
BTW-
Radius is HALF the Diameter.
Diameter is that straight line that goes across the center of the circle.
Radius is basically a line from the center of the circle to any of the side of the circle.
Circumference is basically the perimeter of the circle, or the border or it. It is the Diameter times pi (it said to use 3.14 for pi). It can also be 2 times the Radius times pi (3.14) (since Radius is half the Diameter).
Area is the region inside the circle. Area is the Radius squared (to the power of 2, whatever) times pi (simplified as 3.14).
Okie, now the answers.
^^^Too lazy to put the unit lol.
Answer:
Step-by-step explanation:
d = r * t
Let the time at 59 miles / hour be t
59*t + 57* (4.5 - t) = 259.5 Remove the brackets
59*t + 256.5 - 57*t = 259.5 Combine the left
2t + 256.5 = 259.5 Subtract 228 from both sides
2t = 259.5 - 256.5 Combine
2t = 3 Divide by 2
t = 1.5
So he spent 1.5 hours going at 59 miles per hour
He spent 4.5 - 1.5 = 3 hours going 57 miles per hour.
