Problem 3: Distance = 200 meters, Time = 8 seconds. What is the speed?

The runner ran from A to B to C and D. The distance is​ (a)   and the displacement is ​ (b)   .

• 10 km
• 1 km
• 0 km
• 6km
• 9 km

If an airplane travels 500 km in 5 hours, what is the average speed?

Mathematical Equivalence

ON

Distance is ​ (a)   and Displacement is ​ (b)  

• how far something travels
• how far something travels from the starting point
• how fast you are going
• all in your imagination

Match the following scenarios with their speeds.

• A cyclist covers 320 m in 10 seconds.

• 20 m/s

• A person walks 40 m in 20 seconds.

• 2 m/s

• A car travels 400 m in 20 seconds.

• 32 m/s

What distance did the bike travel if it had a speed of 15.0 m/s over 4.0 seconds?

Mathematical Equivalence

OFF

Match the following

• Acceleration

• The rate at which velocity changes over time.

• Speed

• The rate of change of position in a specific direction

• Displacement

• The total distance traveled divided by the total time taken.

• Velocity

• The overall change in position from the starting point.

Answer explanation

To find the average speed, divide the total distance by the total time. Here, 150 km ÷ 3 hours = 50 km/h. Thus, the average speed of the car is 50 km/h.

• miles
• minute
