Your company is hosting a benefit 5 kilometer race. how long will the race be to the nearest tenth of a mile?

1km=0.62 miles

so multiply 1km by 5 to get 5km
multiply 0.62 by 5 to get km to miles
0.62 times 5=3.1

answe ris 3.1 miles

Well, OK.  My company never hosted anything, certainly
nothing with any benefit, so this scenario doesn't relate
very well to the real world.  But here's the math:

(5 km) x (1 mile / 1.609344 km)  =  3.106... mile

Rounded to the nearest tenth of a mile:

                           3.106... mile  ===>  3.1 mile
