HW #40

Front

What is the formula to calculate distance when speed and time are known?

Back

Distance = Speed × Time

Front

If two objects are moving in the same direction, how can we determine when one will catch up to the other?

Back

Set the distance equations equal to each other and solve for time.

Front

What is the average speed of an object?

Back

Average Speed = Total Distance / Total Time

Front

How do you calculate the speed of a boat in still water if it travels with and against a current?

Back

Speed in still water = (Speed with current + Speed against current) / 2

Front

If a passenger plane leaves before a cargo plane, how do you account for the time difference in their speeds?

Back

Calculate the distance the passenger plane traveled before the cargo plane left, then set up equations based on their speeds.

Front

What is the relationship between speed, distance, and time?

Back

They are interrelated; changing one affects the others.

Front

How do you find the speed of an object if you know the distance it traveled and the time it took?

Back

Speed = Distance / Time

Front

What is the significance of relative speed in problems involving two moving objects?

Back

Relative speed helps determine how quickly one object is approaching or moving away from another.

Front

How can you express the distance traveled by two objects moving in opposite directions?

Back

Total distance = Distance of Object 1 + Distance of Object 2.

Front

What is the effect of current on a boat's speed?

Back

Current can either increase or decrease the effective speed of the boat depending on its direction.
