How Long Does It Take a Car to Travel 250 km at Constant Speed? (Speed & Distance Explained)

When solving travel-related math problems, a common question is: If a car travels 150 km in 3 hours, how long will it take to cover 250 km at the same speed? Understanding how to use speed, distance, and time relationships helps quickly answer such queries.

Step 1: Calculate the car’s speed

Understanding the Context

Speed is calculated using the formula:
Speed = Distance ÷ Time

Given:
- Distance = 150 km
- Time = 3 hours

So,
Speed = 150 km ÷ 3 h = 50 km/h

This means the car travels at a constant speed of 50 kilometers per hour.

Step 2: Determine time required to travel 250 km

Using the same formula, solve for time when distance is 250 km:
Time = Distance ÷ Speed

Plug in the values:
Time = 250 km ÷ 50 km/h = 5 hours

Summary

If a car maintains a steady speed of 50 km/h:
- It travels 150 km in 3 hours
- It will take 5 hours to travel 250 km at the same speed

Final Thoughts

Practical Tip
Speed, distance, and time are directly proportional. Knowing one of the three allows quick calculation of the others—ideal for planning trips, estimating travel time, or optimizing fuel consumption.
