Calculation of Flight Speed

To find the flight speed of the butterfly and the wasp, we need to determine the distance they cover in a given time.

Given information: - The butterfly covers the distance between two flowers in 15 minutes. - The wasp covers the same distance in 18 minutes. - The wasp's flight speed is 1.26 km/h less than the butterfly's flight speed.

Let's assume the distance between the two flowers is d kilometers.

To calculate the flight speed, we can use the formula:

Speed = Distance / Time

For the butterfly: - Distance = d kilometers - Time = 15 minutes = 15/60 hours (since 1 hour = 60 minutes)

For the wasp: - Distance = d kilometers - Time = 18 minutes = 18/60 hours (since 1 hour = 60 minutes)

Now, let's calculate the flight speeds of the butterfly and the wasp.

For the butterfly: Speed of the butterfly = d / (15/60) = 4d km/h For the wasp: Speed of the wasp = (d / (18/60)) - 1.26 = (20d/3) - 1.26 km/h Therefore, the flight speed of the butterfly is 4d km/h and the flight speed of the wasp is (20d/3) - 1.26 km/h.

Please note that the exact value of the distance between the flowers (d) is not provided in the question, so we cannot determine the specific flight speeds of the butterfly and the wasp. However, we have provided the formulas to calculate their flight speeds based on the given information.
