Step 1:: Recall the conversion factor between kilometers per hour (km/h) and miles per hour (mph).
The conversion factor is 1 km/h = 0.621371 mph.
Step 2:: Set up the conversion equation.
The speed limit in miles per hour is equal to the speed limit in kilometers per hour multiplied by the conversion factor. Speed limit (mph) = Speed limit (km/h) × Conversion factor
Step 3:: Plug in the values.
The speed limit is 55 km/h, and the conversion factor is 0.621371. Speed limit (mph) = 55 km/h × 0.621371
Step 4:: Perform the multiplication.
Speed limit (mph) ≈ 34.223955
Step 5:: Round the result to the nearest tenth.
Speed limit (mph) ≈ 34.2
Final Answer
The speed limit on the highway is approximately 34.2 miles per hour.
