How many miles in 620 kms?

One kilometre is equal to 1000 meters.

One mile is equal to 1.6 kilometres.

It is a simple case of using ratios.

Use this and it will help in future

Note the subject "x" represents the value in miles

If 1.6 Km = 1 Mile
Then 620 Km = x Mile

Ignore the units in this regard.

Rearrange so that "x" is the subject

620 = x
1.6 = 1

X = (620 x 1)/1.6

X = 387.5 miles
