Calculating Speed and Distance

Mrs. Layman introduces a math lesson on calculating distance and rate, using the formula distance equals rate times time. The lesson includes examples such as Chris Johnson's 40-yard dash and a road trip scenario to illustrate the concepts. Students learn to choose the appropriate formula based on the problem and are given homework to reinforce the lesson.

What is the basic formula for calculating distance?

• Distance = Time - Rate

• Distance = Rate / Time

• Distance = Rate x Time

• Distance = Rate + Time

In the formula for distance, what does the dot between rate and time signify?

• Division

• Multiplication

• Subtraction

• Addition

If a car travels at 60 miles per hour for 2 hours, how far does it travel?

• 60 miles

• 30 miles

• 120 miles

• 180 miles

What is the rate of speed if Chris Johnson ran 40 yards in 4.24 seconds?

• 9.00 yards per second

• 8.50 yards per second

• 10.00 yards per second

• 9.43 yards per second

When calculating distance, why is it important to convert minutes to hours?

• To avoid using a calculator

• To make the numbers smaller

• To match the units of rate

• To simplify the calculation

If a car travels at 65 miles per hour for 3 hours, what is the total distance covered?

• 130 miles

• 195 miles

• 180 miles

• 210 miles

How do you calculate the rate of speed if you know the distance and time?

• Divide time by distance

• Multiply distance by time

• Add distance and time

• Divide distance by time

What is the distance covered if you travel at 50 miles per hour for 0.25 hours?

• 20 miles

• 10 miles

• 12.5 miles

• 15 miles

If a plane travels at 375 miles per hour for 6 hours, how far does it travel?

• 2250 miles

• 3000 miles

• 2500 miles

• 2000 miles

What formula would you use to find the speed of a mouse that ran 360 centimeters in 9 seconds?

• Speed = Time / Distance

• Speed = Distance / Time

• Speed = Distance + Time

• Speed = Distance x Time
