Answer:
Speed in km/hr will be 109.412 km/hr
Step-by-step explanation:
We have given speed of the car on a highway = 68 mi/hr
We have to find the speed in km/hr
For this first we have to change mi to km
We know that 1 mile = 1.609 km
Speed is the ratio of distance and time
So 68 mi/hr
![=68* 1.609km/hr=109.412km/hr](https://img.qammunity.org/2020/formulas/physics/college/3uhv5g9pm8lq6fbjxakgxdmlc8hefehazj.png)
So the speed in km/hr will be 109.412 km /hr
