Sorry, I'm no good with arithmetic so any help with the below question is appreciated!

If a bike travelled at a constant 15mph, how long would it take it to go 0.8mph?

speed = distance over time, so time = distance / speed.

So the sum you want is 0.8/15 = 0.053 hours, or 3.2 minutes, or 192 seconds.

Quick sanity check: if a car is travelling 15 miles each hour, then 1 mile takes 1/15th of an hour, or 4 minutes. So the answer has to be a bit less than 4 minutes. Which it is.
