Question

choose the correct answer: 5. the speed of the car that moves 30km/h to the east is ____________. 6. a train moves 500 km in 2 hours. the speed of the train is ________.

Explanation:

Step1: Recall speed formula

Speed = Distance/Time

Step2: Solve for car speed

The car's speed is already given as 30 km/h.

Step3: Solve for train speed

For the train, distance \(d = 500\) km and time \(t=2\) hours. Using the formula \(v=\frac{d}{t}\), we have \(v=\frac{500}{2}=250\) km/h.

Answer:

1. 30 km/h
2. 250 km/h
