The equation used to solve problems of this type is one of reciprocals. It is derived as follows: rate ×time = work done rate × time = work done. For this problem: Felicia's rate: F rate × 4 h = 1 room Katy's rate: Krate × 12 h = 1 room Isolating for their rates: F = 1 4 h and K = 1 12 h Felicia's rate: F rate × 4 h = 1 room Katy's rate: K ...
Rate review (article)
Finding unit rates. To find a unit rate, we divide the first quantity in a rate by the second. Example: A plane flew 765 kilometers in 3 hours. 765 ÷ 3 = 255. The plane flew at a rate of 255 kilometers per hour. We can also write the unit rate as 255 km: 1 hour .

For example 78/3=26. However, 78/4=19.5 and since there aren't half biscuits when considering ratios of salty and sweet biscuits, all answers with 4 is wrong eliminating A, and B. C is not the answer because both 5 and 11 does not result in an integer. 78/5=15.6 and 78/11=7.09 eliminating C, thus since D has 5 as well, it cannot be the answer.

Solving unit rate problem (video)
To find the unit rate, we need to convert the rate to be per 1 hour. The unit rate would be: 240 km / 2.5 hours = 96 km/hour. $15 for 4 quarts = $ for 1 quart. To find the unit rate, we need to convert the rate to be per 1 quart. The unit rate would be: $15 / 4 quarts = $3.75/quart. There are 25 computers in a math lab.
