A UBC member can install 7 counters in 22 hours, given that it takes 3 hours to install a single counter.
If one UBC member can install a counter in 3 hours, the number of counters that can be installed in 22 hours can be determined by a simple division. The amount of time available (22 hours) is divided by the time it takes to install one counter (3 hours).
To find out how many counters can be installed, we perform the following calculation:
Divide the total hours available (22 hours) by the number of hours it takes to install one counter (3 hours).
22 hours ÷ 3 hours per counter = 7.333 counters.
Since a UBC member cannot install a fraction of a counter, we only consider the whole numbers, which means the UBC member can install 7 counters in 22 hours.
