George was riding his bike downhill on a street in a Canadian town. The street- side speed sensor clocked him at 30 km per hour. His bike speedometer was set up in U.S. units of mph. What would the readout have been?b. A short-course meter pool is 25 meters long.

Respuesta :

In order to find the readout in his bike speedometer, we need to know the approximate value for the conversion between miles and kilometers, then,

[tex]1\text{ }mi\Rightarrow1.609\text{ }km[/tex]

then, use conversion factors with the street side sensor,

[tex]\frac{30km}{h}\ast\frac{1mi}{1.609km}\approx\frac{18.64mi}{h}[/tex]

Answer:

The approximate value shown in his bike speedometer is 18.64 mph
