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

2400 miles in 13 days and 8 hrs.....there is 24 hrs in a day.....13 days = (24)(13) = 312 hrs...plus the 8 hrs = 320 hrs

so it is 2400 miles in 320 hrs = 2400/320 = 7.5 miles per hr is the average speed.

Answer 2

13 days are equivalent to 13*24 hours;
=312 hours
Total hours;
312 +8
=320 hours
Speed=
`(Distance)/(time)`
Speed=
`(2400 miles)/(320 hours)`
= 7.5 miles per hour
