The average speed of the student for his entire walk is equal to 1.5 m/s. Therefore, option (b) is correct.

What is the average speed?

The average speed of a body is calculated as the total distance traveled in a fixed interval of time. The average speed can be determined by dividing the total distance traveled by a body by the total time.

The average velocity is a single value if the object moves uniformly. Speed is a scalar quantity, it has no specified direction. The average speed has the S.I. unit the same as velocity i.e. m/s.

Given the distance covered by a student in first 80 sec = 100m

After stooping for 30sec again cover a distance of 200m in 90sec.

The total distance traveled by the student = 100 + 200 = 300m

The time taken by student to cover distance =  80 + 30 +90 = 200 sec

The average speed of the student = total distance/ total time taken

                                                          = 300/200 = 1.5 m/s

Therefore, the average speed of the student is equal to 1.5m/s.

ABCD is a parallelogram.
kow [346]

Opposite sides of a parallelogram are equal lengths, so ...

... AB = CD

... 6x +30 = 2y -10

and

... BC = AD

... 2x -5 = y -35

_____

The equations can be put in standard form to get

... 3x -y = -20

... 2x -y = -30

Subtracting the second from the first, we get

... x = 10

Solving for y, we have

... y = 2x+30 = 2·10 +30 = 50

The values of x and y are x=10, y=50.

_____

AB = 6x+30 = 90

BC = 2x-5 = 15
