A turtle swims at a speed of 12 mph. A boy swims at a speed of 4.4 ft per s.

1 answer:

8 0

The turtle`s speed:
v t = 12 miles / hour = /*5,280
= 63,360 ft / hour = / : 3
= 21,120 yards / hour = / : 60
= 352 yards / minute
The boy`s speed:
v b = 4.4 ft/ s = / * 60/3
= 4.4 * 20 yards / minuet = 88 yards / minute
v t : v b = 352 : 88 = 4
The turtle swims 4 times faster than the boy.

Which undefined terms are needed to define a line segment

Finger [1]

Unsure of what you are asking!

But if the issue here is how to define a line segment, write what you do know and then reconsider "undefined terms."

A line segment is a straight line that connects a given starting point and given ending point.

If you consider a circle of radius 3 units, the radius can be thought of as the line segment connecting the center of the circle to any point on the circumference of the circle.

If the center of a given circle is at C(0,0) and a point on the circumference is given by R(3sqrt(2),3sqrt(2)), then AC is the line segment joining these two points. This line segment has length 3 and is in the first quadrant, with coordinates x=3sqrt(2) and y=3sqrt(2) describing the end point of the segment.
