Verified step by step guidance1
Identify the given speed in kilometers per hour (km/h), which is 60 km/h.
Recall the conversion factor between kilometers and miles: 1 mile = 1.609 kilometers.
Set up the conversion from km/h to mph using the formula: \(\text{speed in mph} = \frac{\text{speed in km/h}}{1.609}\).
Substitute the given value into the formula: \(\text{speed in mph} = \frac{60}{1.609}\).
Calculate the division to find the speed in miles per hour, then compare this value to the options provided to determine the closest match.
