Question

A certain species of bird migrates 14,000 miles in 90 days. It rests 8 hours each day and

Answer 1

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
