Question

A ball is rolling across the floor. Every 3 seconds it travels 12 meters. Its speed, therefore, is 36 m/s. Is this problem solved correctly? If not, what is the ball’s actual speed?

Answer 1

No because you are supposed to do this

$d = t)v$
T for time and V for velocity or acceleration so what you do is take the two numbers

D= 3/12 it goes 12 meters every 3 seconds so you devide 12/3
$12 \div 3 = 4$
So for every second the ball roles 4 meters!
Hope this helps! :)
