One butterfly was shown to fly an average of 11.5 mph. about how many days will it take to make the trip not counting rest.

trip distance: 2500 miles

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 =

Time required by butterfly in hours

Now we need to convert number of hours in number of days

As 24 hours = 1 day

So butterfly will need 9.0579 days of flying at speed of 11.5 miles per hour to cover distance of 2500 meters.

2 5/8 is the final answer! : )
