Final answer:
Angela can paint faster.
Step-by-step explanation:
In order to determine who can paint faster, we need to compare the rates at which Jeff and Angela can paint. Jeff can paint 53 square feet every 30 minutes, which is equivalent to a rate of 53 square feet per 0.5 hour. Angela can paint 115 square feet every hour, which is equivalent to a rate of 115 square feet per 1 hour. To compare these rates, we need to convert them to the same unit of time. Since the rates are given in minutes and hours, we can convert Jeff's rate to square feet per 1 hour by multiplying 53 by 2 (since there are 2 30-minute intervals in 1 hour). This gives us a rate of 106 square feet per 1 hour for Jeff. Comparing this to Angela's rate of 115 square feet per 1 hour, we can see that Angela can paint faster.
