A car travelled a distance of D =320 kilometers for T =5.0 hours at a constant rate use the formula D =R. T To find the speed (R
1 answer:
The speed of car is 64 kilometer per hour
<em><u>Solution:</u></em>
Given that car travelled a distance of D = 320 km for T = 5.0 hours
To find: speed (R) of the car in km per hour
<em><u>Formula given:</u></em>
D = R. T
where "D" is the distance
"R" is the speed of car
"T" is the time taken
<em><u>Substituting the given values in above formula we get,</u></em>
Thus the speed of car is 64 kilometer per hour
We cannot round the answer to nearest tenth, since answer is not in decimal

The image lines constructed are called parallel lines. They are parallel because they are all equidistant to each other at every point and at no point between any of the lines will there be an intersection of the three lines.
<h3>What does it mean for two or more lines to be equidistant from each other?</h3>Equidistance is simply another word for equal in distance. That is, parallel lines maintain equal distance from each other at all points along them.
See the attached construction as well as more insights about parallel lines from the link below.

To answer this, we need to use the rules of geometric shapes. An equilateral triangle is equiangular, meaning all its angle measures are equal. Since all triangles' angles add up to 180°, simply divide 180 by three to find the angle measure of each angle:
Therefore, the measure of the triangle's angle is 60°
Next, we know that a characteristic of a rectangle is that each angle must be a right angle, or an angle with a measure of 90°.
Now, all we have to do is use the sum of all the angle measures to figure out the missing piece:
The missing angle measure, angle x, equals 18°.
Hope this helps!
