Here’s you answer mate

Answer:
2.4 days

Step-by-step explanation:
Use the equation
Work done = rate x time
If you can complete the calls in 6 days, then your rate is N/6 calls per day.
By similar reasoning, your classmate has a rate of N/4 calls per day. Working together , we can write:
Combined rate x time = total calls
(N/6 + N/4) t = N
Nt/6 + Nt/4 = N
Multiply both sides by 24/N:
4t + 6t = 24
10t = 24
t = 2.4 } 2.4 days
