Suppose your speedometer has an uncertainty of 4.5 km/h at a speed of 92 km/h. If the speedometer has the same percent uncertainty when it reads 55 km/h, what is the highest speed, in kilometers per hour, that you might be going?    If the speedometer has the same percent uncertainty when it reads 55 km/h, what is the lowest speed, in kilometers per hour, that you might be going?

A study fonds that the metabolic rate of mamals is proportional to the mass of the mamal carried to the exponent of (3/4). By what factor does the metabolic rate of a 70.0 kg human exceed that of a 6.30 kg cat?\ 70.0 3/4 kg    = 6.09 6.303/4 kg I set up the values as a ratio and came up with 6.09. OK, I answered my own question. That is the correct answer.
