an assembly line worker at Rob's Bicycle factory adds a seat to a bicycle at a rate of 2 seat in 11 minutes. At this rate, how long will it take to add 16 seats? 19 seats?
2/11 = 16/x
Cross multiply and solve for x.
2x = 176
x = 88 minutes
Do the second problem the same way.
To find out how long it will take to add a certain number of seats, we need to calculate the amount of time it takes to add one seat and then multiply that by the number of seats required.
We know that the worker adds 2 seats in 11 minutes. Therefore, we can calculate the time taken to add one seat by dividing 11 minutes by 2 seats:
Time taken to add one seat = 11 minutes / 2 seats = 5.5 minutes per seat
Now, we can answer the given questions:
1) How long will it take to add 16 seats?
To calculate the time, we can multiply the time taken to add one seat (5.5 minutes) by the number of seats required (16 seats):
Time to add 16 seats = 5.5 minutes/seat * 16 seats = 88 minutes
Therefore, it will take 88 minutes to add 16 seats.
2) How long will it take to add 19 seats?
Using the same logic as above, we can calculate the time:
Time to add 19 seats = 5.5 minutes/seat * 19 seats = 104.5 minutes
Therefore, it will take approximately 104.5 minutes to add 19 seats.
