first work out the circumference of the wheel
can you do that?

= 2* 3.14 * 80 = ?
50 revolutions per minute = 50 * 502.4 ins per minute
that's how I get stuck! it's inches to miles and minutes to hours... I've tried it about 5 different ways before I posted. (It's multiple choice, so I know my answers are wrong when they aren't there!)
I'm not at my best today - i just said divide by 60 instead of multiply
its 50*502.4 * 60 inches per hour
then as there are 5280 * 12 inches ina mile
mph = 50*502.4 * 60
= 23.79 mph ?
is that a choice?
ahhhh! Thanks found my error. I was forgetting the 50 back in the original formula. Early for me too, apparently.
