If Alvin and Simon raced a distance of
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)](https://tex.z-dn.net/?f=7%282.9%20%5Ctimes%2010%5E2%29)
- Distance travelled =
![2.03 \times 10^3 km](https://tex.z-dn.net/?f=2.03%20%5Ctimes%2010%5E3%20km)
Hence the distance in kilometers in scientific notation ![2.03 \times 10^3 km](https://tex.z-dn.net/?f=2.03%20%5Ctimes%2010%5E3%20km)
