Answer:
The unit rate is 60 miles per hour
The unit rate is 2.5 meters per second
The unit rate is 12 customers per day
The unit rate is 1.592 dollars per pound
Explanation:
* Lets explain how to find the rate
- A rate is the ratio between two related quantities in different units
- To find the unit rate, divide the numerator of the given rate by the
denominator of the given rate
* Lets solve the problem
# 420 miles in 7 hours
∵ The distance is 420 miles in time 7 hours
- The unit rate is how many miles in 1 hour
∴ The unit rate = 420 ÷ 7 = 60 miles per hour
∴ The unit rate is 60 miles per hour
# 40 meters in 16 seconds
∵ The distance is 40 meters in time 16 seconds
- The unit rate is how many meters in 1 second
∴ The unit rate = 40 ÷ 16 = 2.5 meters per second
∴ The unit rate is 2.5 meters per second
# 360 customers in 30 days
∵ There are 360 customers in 30 days
- The unit rate is how many customers in 1 day
∴ The unit rate = 360 ÷ 30 = 12 customers per day
∴ The unit rate is 12 customers per day
# $7.96 for 5 pounds
∵ The cost is $7.96 for 5 pounds
- The unit rate is the cost of per pound
∴ The unit rate = 7.96 ÷ 5 = 1.592 dollars per pound
∴ The unit rate is 1.592 dollars per pound
