<h3>Scale factors</h3>

Scale factors are values or constants multiplied with a variable

If Alvin and Simon raced a distance of $2.9 \times 10^2$ kilometers and they need to race 7 times that distance in a kilometer, the distance traveled will be:

Distance travelled = $7(2.9 \times 10^2)$
Distance travelled = $2.03 \times 10^3 km$

Hence the distance in kilometers in scientific notation $2.03 \times 10^3 km$
