3x + 5x + x = 180

9x = 180

x = 180/9

x = 20

A physics student walks 100 meters in 80 seconds. The student stops for 30 seconds, and then walks 200 meters farther in 90 seco
klio [65]

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.
