Hey there!!
Here's your answer!!!


given,
$d = 900 \: m$
$t = 3 \: s$
we know that
$v = 2d \div t$
therefore,
$v = 2 \times 900 \div 3$
$= > 600 \: mtrs \: per \: sec$

Answer 2

Answer:

660

Explanation:

d=900m

t = 3 \: st=3s

we know that

v = 2d \div tv=2d÷t

therefore,

v = 2 \times 900 \div 3v=2×900÷3

= > 600 \: mtrs \: per \: sec=>600 mtrs persec
