Irina-Kira [14]

Answer:

34.48\text{ miles}

Step-by-step explanation:

GIVEN: A group of robins took 78 days to fly 3000 miles.

TO FIND: On average about how many miles did the robins flight each day.

SOLUTION:

Total number of days taken by robins to fly the distance =78

Total distance traveled by robins =3000\text{ miles}

Now,

Average miles robins flights each day =\frac{\text{total miles traveled by robin}}{\text{total days taken}}

                                                               =\frac{3000}{78}

                                                               =34.48

Hence robin flight average 34.48 miles each day.
