Question

how long will your trip take in hours if you travel 350 km at an average speed of 80 km per hour

Answer 1

Our setup looks like this:

x * ^{80 km} / _hour = 350 km

Let's multiply that kph out to move it to the other side and isolate the hours:

x * ^{80 km} / _hour * ^hour / _{80 km} = 350 km * ^hour / _{80 km}

We can factor out a 10 and kilometers:

x = ^{35 hours} / ₈

x = 4 ³/₈ hours to take the trip
