I get A as an OA. Can anyone confirm please, I tend to struggle with rate questions. Amount=Rate*Time 1=Rate*2Rate=1/2 so 1/2*10=5, hence 5 people should be hired

I found this to be really tricky. I got it wrong at first because I didn't convert minutes and hours. It takes 1 person to finish one task in 2 hours. Convert this to 2*60 = 120 minutes. How many people to finish the same task in ten minutes? Well, if it takes 1 person 120 minutes to finish the task, then in ten minutes they will finish 10/120 = 1/12 of the task. If one person can finish 1/12 in ten minutes, then it will take 12 people to finish 12/12. So the answer is C, 12 people. Quote: 1 person * (10 min/120 min) project * x people = (12/12) project x = 12

work = rate x time 120 = 1 x 120
work = rate x time 120 = r x 10 r = 12
Therefore, the answer is C

A. 5 B. 6 C. 12 D. 20 E. 120 rate of the person = 1/2 per hr or 1/120 per minute rate of n person = n/120 n/120 . 10 = 1 n = 12

A. 5 B. 6 C. 12 D. 20 E. 120 We are given that the rate of 1 person to complete a task is 1/2. We need to determine how many people are needed to complete the task in 10 minutes or 1/6 of an hour. If we let n = the number of people needed, then n x (1/2) = n/2 is the rate of these n people. We can now create the following equation: rate x time = work n/2 x 1/6 = 1 n/12 = 1 n = 12 Answer: C
