If the speedometer in a car reads 78 miles per hour, the car's speed in kilometers per hour is 125.53 kilometers per hour.
<h3>How to convert speed?</h3>
The speed of a car is the measure of the distance moved over a given period of time, hence, it is measured in miles/hour, km/hr, m/s etc.
According to this question, the speedometer in a car reads 78 miles per hour.
Since the conversion factor of kilometers per hour and miles per hour is as follows:
1 kilometer per hour = 0.62 miles per hour
Then, 78 miles per hour = 125.53 kilometers per hour.
Therefore, if the speedometer in a car reads 78 miles per hour, the car's speed in kilometers per hour is 125.53 kilometers per hour.
