Constant Speed

The video tutorial explains how to calculate the distance a runner travels at a constant speed. Initially, the runner covers 800 meters in 5 minutes. By dividing the distance by time, the unit rate is determined to be 160 meters per minute. This unit rate is then used to calculate the distance the runner can cover in 10 minutes, which is 1,600 meters. The lesson demonstrates the application of constant speed in solving distance problems.

If a runner covers 800 meters in 5 minutes, what is the first step to find out how far he runs in 1 minute?

• Add 800 and 5

• Subtract 5 from 800

• Multiply 800 by 5

• Divide 800 by 5

What is the unit rate of the runner's speed in meters per minute?

• 180 meters per minute

• 160 meters per minute

• 170 meters per minute

• 150 meters per minute

How do you calculate the unit rate from a given rate?

• Divide the numerator by the denominator

• Multiply the numerator by the denominator

• Add the numerator and the denominator

• Divide the denominator by the numerator

If the runner maintains a constant speed, how far will he run in 10 minutes?

• 1,400 meters

• 1,200 meters

• 1,800 meters

• 1,600 meters

What concept is used to determine the distance the runner can travel in 10 minutes?

• Deceleration

• Acceleration

• Constant speed

• Variable speed
