Unit Price, Constant Speed, and Unit Rate

Front

What is unit price?

Back

Unit price is the cost per single unit of a product, allowing consumers to compare prices effectively.

Front

How do you calculate unit price?

Back

To calculate unit price, divide the total price by the number of units. For example, if a 12-pack of soda costs $6, the unit price is $6 ÷ 12 = $0.50 per soda.

Front

What is constant speed?

Back

Constant speed means traveling the same distance in equal intervals of time, without speeding up or slowing down.

Front

How do you calculate distance when speed is constant?

Back

Distance = Speed × Time. For example, if a car travels at 60 miles per hour for 2 hours, the distance is 60 × 2 = 120 miles.

Front

What is unit rate?

Back

Unit rate is a comparison of any two measurements in which the second term is 1. For example, if a car travels 300 miles in 5 hours, the unit rate is 300 miles ÷ 5 hours = 60 miles per hour.

Front

How do you find the unit rate for miles per gallon?

Back

To find the unit rate for miles per gallon, divide the total miles traveled by the number of gallons used. For example, if a car travels 368 miles on 16 gallons, the unit rate is 368 ÷ 16 = 23 miles per gallon.

Front

If a family spends $70 per month on electricity, how much do they spend in a year?

Back

To find the yearly cost, multiply the monthly cost by 12. $70 × 12 = $840.

Front

What is the formula for calculating speed?

Back

Speed = Distance ÷ Time. This formula helps determine how fast an object is moving.

Front

If a bus travels at a speed of 60 miles per hour, how far will it travel in 3.5 hours?

Back

Distance = Speed × Time = 60 miles/hour × 3.5 hours = 210 miles.

What is the significance of understanding unit rates in real life?

Back

Understanding unit rates helps consumers make informed decisions when comparing prices and evaluating the best deals.
