Question

we rode our bikes 3,500 meters every day for 5 days.How many kilometers did we bike in all.

Answer 1

Well, 3 500m times 5 = 17 500m. To convert, we ask ourselves how many meters in 1km. the answer is 1000m so we move the decimal place over to the left 3 times (there are 3 zeros in 1000). The answer is 17.5km.
