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?

a) 200 km

b) 250 km

c) 450 km

d) 500 km

Explanation:

Step1: Find the speed of the train

Speed is calculated by the formula \( \text{Speed} = \frac{\text{Distance}}{\text{Time}} \). Given that the train traveled 250 km in 5 hours, so the speed \( v=\frac{250}{5}=50 \) km/h.

Step2: Find the distance traveled in the next 4 hours

Using the formula \( \text{Distance} = \text{Speed} \times \text{Time} \), with speed 50 km/h and time 4 hours, the distance \( d = 50\times4 = 200 \) km.

Step3: Find the total distance from the starting point

The total distance is the sum of the distance traveled in the first 5 hours and the distance traveled in the next 4 hours. So total distance \( D=250 + 200=450 \) km.

Answer:

C) 450 km
