If it takes the wolf 42 minutes and 25 seconds to cover 10,000, what is the wolf's average speed? .
a.
23.5 m/s
b.
3.9 m/s
c.
7.5 m/s
d.
235 m/s

B. 3.9 m/s

Step-by-step explanation:

In seconds, 42 min, 25 sec (s):

(42 min)(60s/1min) = (42)(60) s = 2,520 s

2,520 s + 25 s = 2545 seconds

So now, we can calculate the average speed in meters per second (m/s) :

(10,000 meters) / (2545 seconds) = 3.93 m/s

Please let me know if you want this explained further!

Thanks!
