Step-by-step explanation:
that probably should be your answer
Derrick rode 21 total km.
You can find this by adding the 3 distances together and multiplying by 3. Also remember to watch the units as 500m = .5km.
Sorry, I think you forgot the photo of the problem
If you're comparing 1.435 * 10^(-3) mm to 1.435 * 10^3 mm, then the more reasonable measurement is 1.435 * 10^3 mm since,
1.435 * 10^3 mm = 1435 mm = 1.435 meters
1 meter is about 3.28 feet approximately
So 1.435 meters is slightly larger (about 4.708 feet) which is a fairly reasonable distance between the tracks on a railroad.
-------------------
Something like 1.435 * 10^(-3) mm is equal to 0.001435 mm, which is far less than 1 mm.
