To compare the two proportional relationships, we need to determine the rates at which each person paints walls.
For Andrew:
- He can paint 2 walls in 6.5 hours.
- Thus, his rate of painting is 2 walls / 6.5 hours.
For Tim:
- He can paint 3 walls in 8 hours.
- Thus, his rate of painting is 3 walls / 8 hours.
To make the comparison easier, we can convert both rates to walls per hour.
For Andrew:
- We can calculate the rate of painting per hour by dividing the number of walls (2) by the number of hours (6.5).
- Andrew's rate of painting per hour is 2 walls / 6.5 hours = 0.3077 walls/hour.
For Tim:
- We can calculate the rate of painting per hour by dividing the number of walls (3) by the number of hours (8).
- Tim's rate of painting per hour is 3 walls / 8 hours = 0.375 walls/hour.
By comparing the rates, we can see that Tim has a higher rate of painting per hour (0.375 walls/hour) compared to Andrew (0.3077 walls/hour).
