Answer:
The mid-point of the given line segment is:(5.5,-6.5)
Step-by-step explanation:
let us consider two points A and B with coordinates (a,b) and (c,d) respectively.
let C be the mid point of A and B then then the coordinates of C is given by .
in the given question (a,b)=(9,-8) and (c,d)=(2,-5) so the mid point of these two points are =(5.5,-6.5)
Hence, the coordinates of the midpoint of the line segment with endpoints B(9,-8) and C(2,-5) is (5.5,-6.5).
Answer:
The average speed of the car, in miles per hour, from 17:30 to 19:42, is 119.167 meters per second.
Step-by-step explanation:
Physically speaking, average speed (), measured in miles per hour, is the distance travelled (
), measured in miles, divided by time (
), measured in hours. That is:
(1)
The time needed by the vehicle is:
If we know that and
, then the average velocity of the car is:
The average speed of the car, in miles per hour, from 17:30 to 19:42, is 119.167 meters per second.
