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?

Answer 1

Speed = Mileage/Time

13 days and 8 hours = 13x24 + 8 = 320 hours


Speed = 2400/320 = 7.5 miles/hour

Answer 2

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 :

`\text{Average speed}=\frac{\text{Total distance}}{\text{Total time}}`

As per question,

Total distance traveled = 2400 mile

Total time taken = 13 days 8 hr =
`(13* 24)hr+8hr=320hr`

(1 day = 24 hr)

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

`\text{Average speed}=\frac{\text{Total distance}}{\text{Total time}}`

`\text{Average speed}=(2400mile)/(320hr)=7.5mile/hr`

Therefore, the average speed was, 7.5 mile/hr
