Question

it takes a machine 8 seconds to produce a bolt. Each day, the machine starts producing bolts at 09 30. the machine produce bolts continously every 8 seconds until it stops at 16 10 on the same day. work out how many bolts the machine produce each day

Answer 1

First, we need to calculate the total amount of time the machine runs each day:

Starting time: 09:30

Ending time: 16:10

We can convert the starting time and ending time to minutes:

09:30 = 9 x 60 + 30 = 570 minutes

16:10 = 16 x 60 + 10 = 970 minutes

The total running time of the machine is:

970 - 570 = 400 minutes

Since the machine produces a bolt every 8 seconds, we need to convert the running time from minutes to seconds:

400 x 60 = 24,000 seconds

Finally, we can calculate the number of bolts produced by dividing the total running time by the time it takes to produce one bolt:

24,000 / 8 = 3,000

Therefore, the machine produces 3,000 bolts each day.
