Question

Two laboratory technicians are running product quality tests . One technician takes 6 minutes less than the other . What equation would give the amount of time , t , it would take to run the tests if the technicians work together to split the work on the different tests ? 1/(6t) = 1/x - 1/(x - 6) B 1/t = 1/x + 1/(x - 6) Oct t = x + x - 6 1/t = 1/x - 1/(x - 6)

Answer 1

C. t = x + x - 6

Explanation:

Let the time use by other one technician be x

if the other technician takes 6 minutes less than the first technician, then the time taken by the other technician will (x - 6)

The total amount of time t it would take to run the tests if the technicians work together will be expressed by taking the sum of the time taken by the two technician as shown.

First technician = x

Second technician = x-6

Sum of the time taken

t = x+ (x-6)

Hence option C is correct
