ICSE Class 7 Answered

a man walks a distance of 50m in 1 minute and another 50m in 1.5min is the motion  non uniform also,find his average speed in m/s
Asked by vollalasirichandana | 02 Oct, 2021, 10:18: AM
Expert Answer
Average speed = Total distance travelled/ Total time taken
 
Total distance travelled = 50 + 50 = 100 m 
 
Total time taken = 1 + 1.5 min = 2.5 min = 2.5 x 60 seconds = 150 s 
 
Average speed = 100/150 = 0.66 m/s 
 
The motion carried out by man is non - uniform motion as the velocity is not constant.
