A model railroad train travels at a constant speed of 8 cm/s. How far would the train travel in one minute?

480cm or 0.48m

Explanation:

Given parameter:

Speed of the train = 8cm/s

time of travel = 1minute

Unknown:

Distance traveled = ?

Solution:

Speed is the rate of change of distance with time. This suggests that mathematically;

          Speed =

        Distance covered = speed   x   time

Now to solve for the distance;

  Convert the time to seconds;

              60seconds = 1 minute

  Distance covered = 8cm/s  x 60s = 480cm

Distance covered is 480cm or 0.48m
