Answer:
t = 640
Step-by-step explanation:
tickets are directly proportional to number of hours.
t =kh
we find K.
240 = 3k
we divide by 3 in both sides.
k = 80
we substitute K to find how many tickets.
t =80 × 8
t = 640
it doesn't matter if you chose any two, e.g., you would get the same answer even if you used 5 and 400, or 9 and 720
I believe the answer would be 1086.4
Please give a like if I’m right and tell me in the comments if I’m wrong.
Hope this helped :)
The number of hours it will take both the surveyor and apprentice to complete the same job is 15/56 hours.
<h3>Rate of work</h3>
- Hours it takes the experienced surveyor = 7 hours
- Surveyors rate of work = 1/7
- Hours it takes the apprentice = 8 hours
- Apprentice rate of work = 1/8
If the two work together;
Time taken for both to complete the task = Surveyors rate of work + Apprentice rate of work
= 1/8 + 1/7
= (7+8) / 56
= 15/56 hours
Therefore, the number of hours it will take both the surveyor and apprentice to complete the same job is 15/56 hours.
