Question

if 15 workers can finish a task in 42 hours calculate the number of workers required to complete the task in 30 hours​

Answer 1

Answer:

630

Step-by-step explanation:

they are inversely proportional. Now, assume that the number of workers required to complete the task in 30 hours be “x”. => C = 15 × 42 = 630. So, the number of 21 workers are required to complete the task in 30 hours.
