Question

The distance between the school and the park is 6 km. There are 1.6 km in 1 mile.How many miles apart are the school and the park

Answer 1

As stated 1 mile equals to 1.6 km,
so do calculation to get the 6 km

1 mile = 1.6 km

Then try to divide the 6 km with 1 mile value in km which is 1.6 km so that we know exactly how many miles required to get 6 km

$6 \: \div \: 1.6 \: = \: 3.75$
So the answer is 3.75 miles

To prove this

If 1 mile = 1.6,
Then,
3 miles = (1.6 x 3 ) which produce 4.8 km
0.75 mile = ( 0.75 x 1.6 ) equals to 1.2 km

4.8km + 1.2km = 6km , which proves that
3 miles + 0.75 mile = 6km
