Unit 3A Midterm Review

Front

What is the formula to calculate speed?

Back

Speed = Distance / Time

Front

If a bird flies 35 meters in 10 seconds, how do you find the time to fly an additional 14 meters?

Back

First, find the speed: 35m/10s = 3.5 m/s. Then, use the formula: Time = Distance / Speed. Time = 14m / 3.5m/s = 4 seconds.

Front

How do you determine if a runner meets a speed requirement?

Back

Calculate the speed by dividing the distance by the time. Compare the result to the required speed.

Front

What is the average speed of Tyler if he runs 12 miles in 3 hours?

Back

Average speed = 12 miles / 3 hours = 4 miles per hour.

Front

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

Back

Distance = Speed x Time

Front

How do you find the distance traveled if you know the speed and time?

Back

Use the formula: Distance = Speed x Time.

Front

What is the slope of a line in a graph?

Back

The slope is the ratio of the rise (change in y) to the run (change in x).

Front

If a car travels 420 miles in 8 hours, what is its speed?

Back

Speed = Distance / Time = 420 miles / 8 hours = 52.5 miles per hour.

Front

What does it mean for figures to be similar?

Back

Similar figures have the same shape but may differ in size; their corresponding sides are proportional.

Front

If two sides of a triangle are 3 cm and 6 cm, are they proportional?

Back

Yes, because 3:6 simplifies to 1:2.
