Answer:
The bird moves faster
Step-by-step explanation:
Here, we want to get which of the two moves faster
This is a matter of speed
14,000 to km would be;
14,000/0.62 = 22,581 km
There is a rest of 8 hours per day
So 16 hours is used in moving
for 90 days, the total
time spent moving is 16(90) = 1,440 hours
So, the speed is generally
distance/time = 22.581/1,440 = 15.68215 km/h
For the person
100 minutes is same as 60 + 40 minutes
= 1 hour + 40/60
40/60 = 2/3 = 0.667
So the total
time is 1.667 hours
The speed is thus;
20/1.667 = 12 km/h
Comparing the two speeds, we can see that the bird moves faster
In this exercise we have to identify who has the highest speed, for this it will be necessary to use the definition of distance, in this way we have:
The bird moves faster
Then from the velocity we find that:
[tex]16(90) = 1,440 hours\\ 14,000/0.62 = 22,581 km[/tex]
So, the speed is generally, can be caculated as:
[tex]distance/time = 22.581/1,440 = 15.68215 km/h[/tex]
[tex]20/1.667 = 12 km/h [/tex]
