30. find the unit rate of 183 miles in 3 hours
IF you want me to show the unit rate in miles per hour here is the method to do that:
=> 183 miles / 3 hours = 61 miles per hour.
Thus the unit rate is 61 miles per hour or 61 miles /h
Now, if you want to see the unit rate in miles per minute then here is the method to do that:
=> 1 hour = 60 minutes
=> 3 hours = 180 minutes
=> 183 miles / 180 minutes = 1.02 miles per minute
Answer:
3,375 chairs
Step-by-step explanation:
The weight of 25 folding chairs is 15 kg
Number of folding chairs : weight
= 25 : 15
How many chairs can be loaded on a truck having a capacity of
carrying 2025 kg load?
Let number of folding chairs = x
Number of folding chairs : weight = x : 2025
Equate both ratios
25 : 15 = x : 2025
25/15 = x/2025
Cross product
25 * 2025 = 15 * x
50,625 = 15x
x = 50,625/15
x = 3,375
Number of folding chairs = 3,375 chairs
