Question

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?

Enter your answer as a fraction or as a decimal, without units.

Answer 1

Answer:

Her average speed = 7.5 miles/hour

Explanation:

First, since the required speed unit is miles/hour, we need to make sure that all units given are in miles (for distance) and hour (for time)

We are given that:

Distance covered = 2400 miles

Times taken = 13 days and 8 hours

We know that 1 day has 24 hours

Therefore:

13 days = 13 x 24 = 312 hours

Time taken = 13 days and 8 hours = 312 + 8 = 320 hours

Now, average speed is calculated as the total distance divided by the total time

This means that:

$Average Speed=\frac{Total Distance}{Total Time} = \frac{2400}{320}=7.5$ miles/hour

Hope this helps :)
