Answer:
Five people can finish painting a wall in 5 hours. If only 2 people are available, how many hours do they have to work to finish the same job? what speed
12.5 hr → Ans.
Explanation:
If you read the problem carefully, you can make an equation. And this is inverse proportion. Based on the given conditions, formulate:
⇒ 5 · 5 = 2t
⇒ 25 = 2t
⇒ 25/2 = t
Or
If it takes 5 people 5 hours, then that is 25 hours of painting. (5·5=25)
If there are only 2 people, then they would have to paint for 12.5 hours each. (25/2=12.5)
