An ironworker can weld one point in ½ hour. How many points can he weld in 8 hours?

A. 13 welds
B. 12 welds
C. 11 welds
D. 10 welds

Answer :

To determine how many points an ironworker can weld in 8 hours, we start by understanding how long it takes to weld one point. According to the information provided, it takes the ironworker ½ hour (or 0.5 hours) to weld one point.

Now, we need to find out how many points can be welded in 8 hours. We can do this by dividing the total available time, which is 8 hours, by the time it takes to weld one point.

Here's the step-by-step calculation:

1. Determine the time per weld:
It takes 0.5 hours to weld one point.

2. Find the total number of welds in 8 hours:
Total hours available = 8 hours
Time per weld = 0.5 hours
Number of welds = Total hours ÷ Time per weld
Number of welds = 8 ÷ 0.5 = 16

Therefore, the ironworker can weld 16 points in 8 hours. This means the correct answer is 16 welds, which is not listed among the given choices, so it seems there might be an error in the choices provided.
