If a canada goose completes a 2400-mile migration in exactly 13 days and 8 hours, then what was her average speed for the whole trip in miles per hour?

Answer : The average speed was, 7.5 mile/hr

Explanation :

Average speed : It is defined as the ratio total distance to total time.

Formula used :

As per question,

Total distance traveled = 2400 mile

Total time taken = 13 days 8 hr =

(1 day = 24 hr)

Now put all the given values in the above formula, we get:

Therefore, the average speed was, 7.5 mile/hr

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
