Explanation:

velocity = displacement/time

=30/4

=7.4 m/s

mark me as brainliest

Answer 2

Answer:

given:

distance = 4km

time taken = 30 minutes = 30 / 60 hr {we need to convert min to hr}

to find:

velocity = ?

we know,

velocity = distance/ time

calculation :

v = 4//30/60

v = 4//1/2

v = 2 x 4

v = 8km/hr
