Unit Rate Problem Solving Challenge

In this lesson, Mrs. Marcellus teaches students how to solve unit rate problems, including those involving constant speed and unit price. The video covers examples such as a football player's running speed, a jet's flight time, the cost of Swiss cheese slices, glass panes for a nursery, and speaker wire. Each example demonstrates how to calculate unit rates and apply them to solve real-world problems.

If a football player runs 80 yards in 25 seconds, what is his speed in yards per second?

• 3.2 yards/second

• 3.8 yards/second

• 3.5 yards/second

• 3.0 yards/second

How far will the football player run in 60 seconds at the same speed?

• 192 yards

• 180 yards

• 200 yards

• 190 yards

How long will it take for a jet to fly 2125 miles if it flies 25 miles per minute?

• 80 minutes

• 90 minutes

• 75 minutes

• 85 minutes

What is the unit rate of speed for the jet if it flies 175 miles in 7 minutes?

• 22 miles/minute

• 30 miles/minute

• 20 miles/minute

• 25 miles/minute

What is the unit price of Swiss cheese per slice if 24 slices cost $7.20?

• 25 cents

• 40 cents

• 35 cents

• 30 cents

How much will it cost for 5 slices of Swiss cheese?

• $2.00

• $1.50

• $1.75

• $1.25

If the unit price per pane of glass is $2.15, what is the cost for two more panes?

• $4.00

• $4.50

• $4.20

• $4.30

If a nursery owner needs to buy two more panes of glass, how much will he pay if each costs $2.15?

• $4.50

• $4.20

• $4.30

• $4.00

How much will Jaden pay for an additional 30 feet of speaker wire if the unit price is 26 cents per foot?

• $8.00

• $7.60

• $7.80

• $7.50

What is the total cost for 70 feet of speaker wire if the unit price is 26 cents per foot?

• $17.50

• $18.20

• $19.00

• $18.00
