Answer:
a. 3/28 hours
b. 9 tasks
Explanation:
a. The robot can complete 7 tasks in 3/4 hours.
The number of hours it will take to complete one task is:
= Time taken / Number of tasks
= 3/4 ÷ 7
= 3/4 * 1/7
= 3/28 of an hour
b. If the Robot can complete one task in 3/28 of an hour, in one full hour it will complete:
= 1 ÷ 3/28
= 9.33
= 9 tasks
