Answer:
a) 5/18 hour
a) 3 3/5 tasks
Step-by-step explanation:
A robot can complete 3tasks in five sixth hour. Each task takes the same amount of time.
a. How long does it take the robot to complete one task?
3 tasks => 5/6 hour
1 task => x
3x = 1 × 5/6 hour
x = 5/6 ÷ 3
x = 5/6 × 1/3
x => 5/18 hour
b. How many tasks can the robot complete in one hour?
5/6 hour = 3 tasks
1 hour =>x tasks
5/6x = 1 × 3
x = 3 ÷ 5/6
x = 3 × 6/5
x = 18/5
x = 3 3/5 tasks
