Speed, Distance, and Time Problems

This video tutorial by Mr. Hul covers Lesson 22, focusing on speed, work, and measurement units. It explains how to calculate speed using the formula distance equals rate times time, with examples involving a walker and a runner. The lesson also includes unit conversion and exercises on calculating distance for a car on cruise control and in a construction zone.

What is the formula to calculate distance when an object moves at a constant speed?

• Distance = Rate + Time

• Distance = Rate x Time

• Distance = Rate / Time

• Distance = Rate - Time

If a walker covers 50 feet in 8 seconds, what is their speed in feet per second?

• 5.25 feet per second

• 6.25 feet per second

• 7.25 feet per second

• 8.25 feet per second

What is the inverse operation of multiplication used to isolate a variable in an equation?

• Division

• Addition

• Multiplication

• Subtraction

• 10.5 miles

• 13.5 miles

• 11.5 miles

• 12.5 miles

What is the equivalent of 15 minutes in hours?

• 0.15 hours
