A car speedometer has a 8% uncertainty. What is the range of possible speeds (in km/h) when it reads 63 km/h?

A car travels at 61 km/h and covers a distance of 32.904 m. How long in minutes did it take the car to travel this distance?distance?It only places the numerical value, WITHOUT UNITS.Use at least 4 DECIMALS for the procedure.Place only 2 DECIMALS in the result without rounding.

A rectangle has a length of (5.1 ± 0.2) m and a width of (2.3 ± 0.1) m. Calculate: (a) the area and (b) the perimeter of the rectangle, Give the uncertainty in each value.

A car speedometer has a 3% uncertainty.  What is the range of possible speeds when it reads 100km? Km/h (lowest) Km/h (highest) Convert this miles per hour  mi/h (lowest)   mi/h (highest)

Part II. Significant Figures The significant figures in a number are all figures that are obtained from the measuring process and exclude those zeros that are included solely for the purpose of locating the decimal point. This definition will be clarified with a number of examples.

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?
