Answer 1

We will use conversion factors

1 hour = 60 minutes

We need to make sure to put them so the units cancel

We also know that 1,61 km = 1 mi

1.81 km 60 min 1 mi

---------- * ----------- * ---------------

min 1 hr 1 . 61 km

67.45341615

Rounding to the nearest hundredth

67.48 miles/ hr
