A computer can perform c calculations in s seconds. How many minutes will it take the computer to perform k calculations?

c calculation = s seconds

1 calculation = s/c seconds

therefore for "k" calculation

k calculation = k * (s/c) seconds

convert it into minutes

k calculation = (k * (s/c)) / 60 minutes

Explanation:

Since "c" calculation takes "s" seconds by a computer. Then 1 calculation will take "s/c" seconds. If we have to find the time for "k" calculation Then multiply "k" with "s/c". it will give the time for "k" calculation. Then convert it into minutes by dividing 60. This will be the time in minutes for "k" calculation.
