dimaraw [331]

The distance in kilometers in scientific notation 2.03 \times 10^3 km

<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
