Afinch rides on the back of a galapagos tortoise, which walks at the stately pace of 0.060 m/s. after 1.0 minutes the finch tires of the tortoise's slow pace, and takes flight in the same direction for another 1.3 minutes at 12 m/s

The average speed is

Explanation:

The question is

What was the average speed of the finch for this 2.3-minute interval?

we know that

To determine the average speed divide the total distance by the total time

Let

x ----> the total distance in meters

y ----> the total time in seconds

s ----> average speed in m/sec

so

step 1

Find the total distance x

To find the distance multiply the speed by the time

For the first 1.0 minutes

1 minute=60 sec

x=0.060(60)=3.6 m

For the other 1.3 minutes

1 minute=60 sec

x=12(60*1.3)=936 m

the total distance is

x=3.6+936=939.6 m

step 2

Find the total time y

y=(1+1.3)(60)=138 sec

step 3

Find the average speed

substitute the values

i think they are all correct

explanation:

they seem good

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
