Many amtrak trains can travel at a top speed of 47.0 m/s. assuming a train maintains that speed for several hours, how many kilometers will the train have traveled after 5.00 hours? round to the nearest km.

846 km

Explanation:

Speed = 47 m/s

time = 5 hours = 5 x 60 x 60 seconds

Distance = speed x time

Distance = 47 x 5 x 60 x 60

Distance = 846000 m

Distance = 846 km

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.
