Question 1108926
There are approximately 1.6 kilometers in 1 mile. What is the distance, in miles, of 89 kilometers?
89 km/1 mile/1.6 km = 89/1.6 km =~ 55.6 miles
Notice how the units cancel.
-----
Use a proportion to solve and hound your answer to the nearest tenth of a mile 
1/1.6 = miles/89
Multiply by 89
miles = 89/1.6
Same as above.
