Question

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

Answer 1

480cm or 0.48m

Step-by-step 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)/(time)`

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
