The area, A square feet, of the wall Ivan is painting is directly proportional to the time he spends painting the wall, T hours.
It takes Ivan 4 hours to paint 113.6 feet of the wall. How long will he take to paint 227.2 square feet of the wall?
1 answer:
Answer: 4 hours
Step-by-step explanation: Square feet of the wall F²∆ T
F² = KT
113.6² = K4
K= 12,904.96
Time to paint 227.2 is;
F² = KT
227.2² = 12,904.96x T
T = 51,619.84/12,904.96
T= 4 hours
