In general , While estimating a bodies temperature that temperature is not the same for long, the temperature of the body is not at homeostasis, the temperature constantly has bumps and drops in the temperature this causes in accuracy thats why the thermometer takes 10-20 seconds because it takes the average of all the temperature's so it is accurate, that is a difficulty when estimating temperature because estimates are not good and the temperature keeps having ups and downs.
So. We know that Mike paid 71 dollars. We also know that NO MATTER WHAT. He has to pay 17 dollars. So 71-17 is 64. Now, all we need to do is divide 64 dollars, by 6 dollars, to give us the number of hours.
64/6 = 10.6 So Mike had the bike for 10.6 (approxamently) hours.
