Question

How much longer in percentage is a one mile race than 1500 m race?

Answer 1

We known that ,

1 mile =1.609344 km and 1 km =1000m

$\therefore 1$ mile $=1.609344× 1000$ m

$=1609.344$ m

Therefore , 1 mile is 109.344 m more than 1500 m.

Let $x$ % of 1500 m is 109.344 m

Then $1500×\frac{x}{100}=109.344$

$\implies x=\frac{109.344}{15}=7.2896$ %

Hence , 7.2896% longer 1 mile than 1500m
