Question

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?

Expert Solution

Step 1

$Speed (u) = 92 \frac{k m}{h r} Uncertainty = 4.5 \frac{k m}{h r} Percentage uncertainty = \frac{4.5 \times 100}{92} = 4.89 %$
