A group of robins took 78 days to fly 3000 miles. On average about how many miles did the robins flight each day? Explain why your estimate is reasonable.

Step-by-step explanation:

GIVEN: A group of robins took days to fly 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

Total distance traveled by robins

Now,

Average miles robins flights each day

Hence robin flight average miles each day.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
