Distance vs Time

A helicopter traveled 200 miles in one hour. During the next hour, it traveled another 200 miles. Which best describes the average speed of the helicopter during the second hour?

• slower than the first hour
• faster than the first hour
• about the same as the first hour
• exactly the same as the first hour

Which information is needed to determine the speed of an object?

• the weight of the object and the the pull of gravity on the object and the amount of time it travelsdistance it travels
• the pull of gravity on the object and the amount of time it travels
• the inertia of the object and the amount of force that is pushing it
• the distance the object travels and the time it takes to travel that distance

Suzy’s trip to the store takes 30 minutes. She stays inside the store for 10 minutes before returning home. She follows the exact same route home, making her total trip time one hour and twenty minutes. Which statement best describes Suzy’s motion?

• She slows down on the return trip.
• She speeds up on the return trip.
• Her speed remains constant.
• Her speed gains momentum.

What is speed?

• how far you go
• how much distance is covered over a period of time
• how fast you accelerate
• the change in the location of a object
