Ratio of Speeds: Train and Car
To find the ratio of the speed of a train to the speed of a car, we need to divide the speed of the train by the speed of the car. Given that the train's speed is 120 km per hour and the car's speed is 90 km per hour, we can calculate the ratio as follows:
Ratio = Speed of Train / Speed of Car
Ratio = 120 km/h / 90 km/h
Simplifying this expression, we divide both the numerator and denominator by the greatest common divisor of 120 and 90, which is 30:
Ratio = (120 km/h / 30) / (90 km/h / 30)
Ratio = 4 / 3
Therefore, the ratio of the speed of the train to the speed of the car is 4:3.
Explanation:
- The question asks for the ratio of the speed of a train to the speed of a car.
- The speed of the train is given as 120 km per hour.
- The speed of the car is given as 90 km per hour.
- To find the ratio, we divide the speed of the train by the speed of the car.
- Simplifying the expression by dividing both numerator and denominator by the greatest common divisor, we obtain the ratio of 4:3.
- This means that for every 4 units of speed the train travels, the car travels 3 units of speed.
