Answer:
Butterfly will need 9.0579 days of flying at speed of 11.5 miles per hour to cover distance of 2500 meters.
Solution:
Speed of butterfly = 11.5 miles per hour
Butterfly should complete a trip of distance = 2500 miles
Need to calculate number of days (without counting rest)
As time required =
![(distance)/(speed)](https://img.qammunity.org/2020/formulas/mathematics/college/78gdd95chkyckagrqbybhy1jh0nkahp2k3.png)
Time required by butterfly in hours
![= (2500)/(11.5) = 217.3913 hours](https://img.qammunity.org/2020/formulas/mathematics/middle-school/t48vkumzr1ekga84pygqyl14g6p6qcoi5c.png)
Now we need to convert number of hours in number of days
As 24 hours = 1 day
![\text { So } 1 \text { hour }= (1)/(24) days](https://img.qammunity.org/2020/formulas/mathematics/middle-school/tgz5hmipmo7rxbhpuypmvudi6pli8cln2y.png)
![\text { So } 217.3913 \text { hours }=(1)/(24) * 217.3913=9.0579](https://img.qammunity.org/2020/formulas/mathematics/middle-school/bl639wx7qq3lnoc7ydxr9gtnb03c7uhjmz.png)
So butterfly will need 9.0579 days of flying at speed of 11.5 miles per hour to cover distance of 2500 meters.
