Question

A carpenter made 9 equal boxes in 10 h 5 min 15 sec. How much time did he spend making each box?

Answer 1

Answer:

1 hour 7 min and 25 sec

Step-by-step explanation:

the carpenter takes 36, 315 sec to make 9 boxes now we have to find the time he takes for 1 box

so,

9 box = 36,315 sec

1 box = 36,315÷ 9 =4,035 sec

4,035 sec in min = 67. 25 min

ie 1 hour 7 min and 25 sec
