Question

Using the approximation of 5 miles = 8 km
How many km is 12.5 miles?​

Answer 1

Given :-

5 miles = 8 kilometres

To Find :-

How much kilometres is 12.5 miles

For this, we will use Cross Multiplication Method.

We will take kilometres as X.

Miles Kilometres

5 8

12.5 X

Now,

5X = 100

X = 20

Hence, if 5 miles = 8 kilometres then 12.5 miles = 20 kilometres.
