Many amtrak trains can travel at a top speed of 42.0 m/s. assuming a train maintains that speed for several hours, how many kilometers will the train have traveled after 4.00 hours? round to the nearest km.

605 km

Explanation:

Hello

the same units of measure should be used, then

Step 1

convert  42 m/s ⇒   km/h

1 km =1000 m

1 h = 36000 sec

Step 2

find kilometers traveled after 4  hours

V,velocity

s, distance traveled

t. time

now, isolating s

and replacing

S=604.8 Km

Have a great day
