Question

In 600 minutes how many machines travel a distance of 103,700 mm at a speed of 300 mm/minute?

Answer 1

I think you're missing something here. We can figure out how long it takes to go 103700mm, but that tells us nothing about how many machines are involved.

If the question is how far a machine can go in 600min, that would be twice as far as it goes in 300 min...
