Gnesinka [82]

Answer:

6/1 square feet per hour. Jeff can paint faster.

Step-by-step explanation:

So, to get Jeff's square feet to 60 minutes, you do 30x2= 60. So, you do that to 28. 28x2= 56. 56/1 is greater then 50/1. So 56-50= 6. Jeff can paint 6 square feet per hour, greater than Angela.

Hope this helped!

So, Quotient = Dividend ÷ Divisor

by using the above relation we can say :

q = t ÷ 23

therefore, correct option is C. t ÷ 23
