The speed of a train which covers 200 kilometre in 4 hours is

Options

A. 30 km `h^(-1)`
B. 50 km `h^(-1)`
C. 80 km `h^(-1)`
D. 70 km `h^(-1)`

Explanation

To find the speed of a train that covers 200 kilometers in 4 hours, we can use the formula for speed:

**Speed = Distance / Time**

Step 1: Identify the distance traveled by the train.
- The distance covered by the train is 200 kilometers.

Step 2: Identify the time taken to cover that distance.
- The time taken is 4 hours.

Step 3: Substitute the values into the speed formula.
- Speed = Distance / Time
- Speed = 200 kilometers / 4 hours

Step 4: Perform the division to calculate the speed.
- Speed = 50 kilometers per hour (km/h)

Thus, the speed of the train is **50 km/h**.
