Question

4. A boy walks a distance of 30 m in 1 minute and
another 30 m in 1.5 minute. Describe the type of
motion of the boy and find his average speed
in m s-1​

Answer 1

Hola mate...✌️✌️✌️✌️

$\huge \purple {ANSWER}$

_______________________________________

The type of motion is non uniform motion.

:. average speed = total distance ÷ total time

=(30 m+30m) ÷ (1 min +1.5 min)

= 60 m ÷2.5 min

=24m/min

= 24m/60 s

=0.4 m/s

Answer 2

Answer:

average speed : 0.4 m/s

Explanation:

average speed=Total distance/Total Time

as we have given,

total distance = 30+30=60

total time in second=(1.5+1)*60

therefore on solving,

Average speed=60/(2.5*60)= 0.4m/s
