velocity = distance travelled over time
Strictly speaking in physics velocity and speed are not quite the same thing. Velocity should be stated with direction. If there is no direction stated then in physics it is called speed. In everyday language we use either term.
velocity = 2345m / 315s
= 7.4 m/s
= 26.8 km/hr
= 16.6 mi/hr (1 km = 0.6213 miles)

315
DISTANCE + VELOCITY x TIME So if you travel 90 miles in two hours, 90 = velocity x 2 velocity = 45 miles per hour After 7 hours DISTANCE = 45 x 7 = 315 miles
21% of 315= 21% * 315= 0.21 * 315= 66.15
315% = 3.15 315 = 31,500%
The LCM is: 315
