Final answer:
The car traveling at 42 m/s will go approximately 93.20628 mph in one hour.
Step-by-step explanation:
To calculate the distance traveled by a car in one hour, you need to know the speed of the car. In this case, the speed is given as 42 m/s. To convert this speed to miles per hour, we need to use the conversion factor. 1 meter is approximately equal to 0.000621371 miles. So, to convert from meters per second to miles per hour, we multiply the speed by 2.23694 (which is the conversion factor from m/s to mph). Therefore, the car traveling at 42 m/s will go approximately 93.20628 mph in one hour.
