Distance = 7 cm = 7/100 m
Time = 5 sec.
velocity = ?
v = d/t
= 7/100/5
= 7/100× 5
= 0.35 m/s
Time = 5 sec.
velocity = ?
v = d/t
= 7/100/5
= 7/100× 5
= 0.35 m/s

Hey there!!
We're given that the distance is 7cm. Which should, apparently, be in metres.. That makes it 7/100 m. (Or 0.07) But Let's just take it in fractions, so as to not fiddle with the decimals so soon.
Time = 5 sec. (given)
We know that, speed= distance/time
V= D/t
= 7/100 / 5
= 7/500
Now you can convert it to decimals
= 0.35 m/s
Hope it helps! :)
