Question

A train traveled 250 kilometers (km) from its starting point in 5 hours (h). If the train continues at the same average speed for another 4 hours, how far will it have traveled from its starting point?

Multiple choice question.

A)
200 km


B)
250 km


C)
450 km


D)
500 km

Answer 1

To find the total distance traveled by the train, we first need to calculate its average speed.

The average speed \( v \) of the train can be calculated using the formula:

\[
v = \frac{\text{distance}}{\text{time}}
\]

Given that the train traveled 250 kilometers in 5 hours:

\[
v = \frac{250 \text{ km}}{5 \text{ h}} = 50 \text{ km/h}
\]

Now, if the train continues traveling at this average speed for another 4 hours, we can calculate the distance traveled during this additional time:

\[
\text{Distance} = \text{speed} \times \text{time} = 50 \text{ km/h} \times 4 \text{ h} = 200 \text{ km}
\]

Now, we add this distance to the initial distance of 250 km:

\[
\text{Total distance} = 250 \text{ km} + 200 \text{ km} = 450 \text{ km}
\]

Therefore, the train will have traveled **450 km** from its starting point.

The correct answer is:

**C) 450 km**
