Runner's Speed and Unit Rate

The video tutorial explains how to calculate the speed of a runner traveling at a constant speed. It begins by determining the rate at which the runner covers 800 meters in 5 minutes. The tutorial then introduces the concept of unit rate, showing how to calculate the distance the runner travels in one minute. Finally, it applies this unit rate to determine how far the runner can travel in 10 minutes, reinforcing the understanding of constant speed and unit rate calculations.

If a runner covers 800 meters in 5 minutes, what is the rate of speed in meters per minute?

• 150 meters per minute

• 170 meters per minute

• 180 meters per minute

• 160 meters per minute

What is the first step in determining the speed of the runner per minute?

• Subtract the total time from the total distance

• Divide the total distance by the total time

• Multiply the total distance by the total time

• Add the total distance and total time

How do you calculate the unit rate for the runner's speed?

• Divide the distance by the time

• Divide the time by the distance

• Add the distance and time

• Multiply the distance by the time

What is the significance of a unit rate in this context?

• It calculates the total time for the journey

• It indicates the speed per unit of time

• It measures the time taken for the journey

• It shows the total distance covered

If the runner continues at the same speed, how far will they travel in 10 minutes?

• 1,600 meters

• 1,400 meters

• 1,800 meters

• 1,200 meters

What is the relationship between time and distance when speed is constant?

• Distance decreases as time increases

• Distance increases proportionally with time

• Distance is unrelated to time

• Distance remains the same regardless of time
