A migrating bird flies 468 miles in 13 hours. how many miles does it fly in 3 hours?
ruslelena [56]

Answer:

The answer is 108mi

Step-by-step explanation:

to solve this problem, we need to write a ratio.

\frac{468mi}{13hrs}

to solve for 3 hours, we need to figure out how many miles the bird can fly in 1 hour. to do that, we need to divide the numerator and denominator by 13.

\frac{36mi}{1hr}

now we have a unit rate that represents distance covered per hour.

to solve for 3, we need to multiply the numerator and denominator by 3.

\frac{108mi}{3hrs}

the question is asking for <u>miles.</u> therefore, the bird can fly 108mi in 3 hrs.

hope this helps!

krok68 [10]

Answer:

a = 73.84, b = -23.64, c = 83.97, d = 21.73

Step-by-step explanation:

1880:

The predicted value is:

f(80) = 1.363\cdot (80) - 35.2

f(80) = 73.84

The residual value is:

\Delta f = 50.2 - 73.84

\Delta f = -23.64

1920:

The predicted value is:

f(120) = 7.8 \cdot 1.02^{120}

f(120) = 83.97

The residual value is:

\Delta f = 105.7 - 83.97

\Delta f = 21.73
