Speed and velocity

What two measurements are needed to calculate average speed?

• Distance and Time

• Volume and Mass

• Mass and Time

• Speed and Distance

Calculate the speed:
A Car traveled 240 Km in 5 Hours

• 48 Km/Hr
• 1200 Km/Hr
• 4.8 Km/Hr
• 0.02 Km/Hr

What is the formula for average speed?

• Average Speed = Total Time undefined Total Distance

• Average Speed = Total Time + Total Distance

Jane jogs 18 km in 2 hours. Then she walks for 6 km in 2 hours. Find her average speed.

• 9

• 3

• 12

• 6

A storm is moving toward your house at a speed of 20 km/hr. It is now 60 km away from your house. How long will it take the storm to reach your house?

• 0.3 hours

• 1200 hours

• 3 km

• 3 hours

Ahmad participated in a biathlon which required him to run 5km and swim 1 km. If he took 1.5 hrs to complete the race, find his average speed for the biathlon.

• 4 km/h

• 6 km/h

• 3.33km/h

• 9km/h

Which is true?

• Speed is measured in m/s but velocity is measured in s/m

• Speed is a vector and velocity is a scalar

• Speed and velocity are the same exact thing

• Speed is like velocity but without a direction

What is a difference between distance and displacement

• Distance is measured in seconds and displacement is measured in meters

• Distance is always shorter than displacement

• Displacement can be equal to zero if the object ends in the place it began in

• Distance can be equal to infinite when only a small distance has been travelled

An astronaut travels at a speed of 400 m/s for 250 seconds, what is the total distance he traveled?

• 0.625 m

• 100,000 m

• 1.6 m

• 650 m

A horse follows a dangling carrot for 20 m, if it took her 50 seconds to reach it, what was her average velocity?

• 1,000 m/s

• 2.5 m/s

• 0.4 m/s

• 20 m/s
