Final answer:

To find the truck's speed in km/h, multiply the given speed in m/s (41.9) by 3.6 to get 150.84 km/h.

Step-by-step explanation:

To convert the speed of the truck from meters per second to kilometers per hour, we use the conversion factor where 1 m/s is equal to 3.6 km/h. If a truck with a radius of 0.420m tires travels at a speed of 41.9m/s, we multiply this speed by the conversion factor to find the speed in km/h:

Speed in km/h = Speed in m/s × Conversion factor

Speed in km/h = 41.9 m/s × 3.6 km/h per m/s

Speed in km/h = 150.84 km/h

Therefore, the truck's speed in kilometers per hour is 150.84 km/h, which corresponds to option 1)
