The humpback has traveled for the same rate for 32 days How many more miles but they have traveled in the hump whale
A. 128
B. 192
C. 280
D. 408

-78 miles or 78 miles (depending on your question)

Step-by-step explanation:

I don't know any shortcuts for these, so I'm sorry if this isn't the technique you're looking for. I'll just do this in the most tedious way ever.

Step 1:

2240 / 28

2240/28 = 80

28/28 = 1

80 / 1

Step 2:

80 / 1

80 * 32 = 2560

1 * 32 = 32

2560 / 32

Step 3:

*If how many more miles for HUMPBACK*

2560 - 2638

-78 miles

*If how many more miles for GRAY*

2638 - 2560

78 miles

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
