Final answer:
In Rate of work Wilma and Bullwinkle can mow the lawn together in approximately 26.67 minutes.
Explanation:
To find out how long it would take for Wilma and Bullwinkle to mow the lawn together, we can use the concept of work rates. Let's first find out how much of the lawn each person can mow in one minute. Since Wilma can mow the lawn in 40 minutes, her work rate is 1/40 of the lawn per minute. Similarly, Bullwinkle's work rate is 1/80 of the lawn per minute.
When they work together, their work rates are combined. So, the total work rate for Wilma and Bullwinkle is 1/40 + 1/80 of the lawn per minute, which simplifies to 3/80 of the lawn per minute.
To find the time it takes for both of them to mow the lawn, we can divide the total work by their combined work rate: 1 / (3/80) = 80/3 minutes, which is approximately 26.67 minutes.
