Write the ratio as a unit rate. 286 miles in 5 and one-half hours a. 36 miles per hour b. 52 miles per hour c. 57.2 miles per hour d. 114.4 miles per hour

divide 286 by 5 1/2

286 / 5.5 = 52

 Answer is B

it could be a ..idk tho

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
