Question

A multisport race consists of 600 metres of swimming, 800 metres of running, and 400 metres of bicycling. The total distance to be covered by an athlete is
km

Answer 1

Total distance of the racing event
$=(600+800+400)$ meters
$=1800\text{meters}$

$1\text{kilometer}=1000\text{meters}$
$\therefore 1800\text{meters}=\frac{1800}{1000}=1.8\text{km}$
