Answer 1

Answer:

$\fbox{given}$

D1= 20m

D2= 30m

T1= 5 sec

T2= 5 sec

$\fbox{</em><em>⛄</em><em>To</em><em> \: Find}$

average speed

$\fbox{solution}$

average speed = total distance/ total time

average speed = 20+ 30/5+5

average speed= 50/10

average speed= 5 m /sec

Therefore,

$\fbox{option \: b \: is \: correct}$
