Question

How long would it take to travel 37 km at a speed of 6000 m/hr?

Answer 1

First you want to convert 6000 m/hr into km/hr, for this, we use dimensional analysis:\[\frac{ 6000m }{ 1hr } *\frac{ 1km }{ 1000km }\]

Answer 2

6000/1000? @Lord_Box

Answer 3

Yes, and the units should cancel out to m/hr (the bottom km should me m, sorry)

Answer 4

\[\frac{ 37km }{ 1 }*\frac{ 1hr }{ 6km }\]

Answer 5

how did you get that? @lord_box

Answer 6

On the first step, we converted 6000m/hr to 6km/hr

Answer 7

And so we can reason that if 6 km takes 1 hour, then 37 km should take 37/6 hours.

Answer 8

So the answer in 37/6?
