Answer:
All of the above.
Step-by-step explanation:
The way to calculate velocity is d/t, the displacement over time of travel. Hence, both of those are needed.
Finally, velocity also needs to know your direction, like 5 m/s East for example. Hence, all of the above are needed.
Hope this helped!

#Lets just write x as the nunber you asked
x × 40/100 = 18
x = 18 : 40/100
x = 18 × 100/40
y = 1800/40
y = 45
