Question

Un automobil se deplaseaza intre orasele A si B cu o viteza conastanta de 30m/s in timp de 20 min. distanta dintre orasele A si B este????

Answer 1

v=30m/s
t=20 min
d=?
v=$\frac{d}{t}$
30m/s=$\frac{d}{20 min}$
30m/s=$\frac{d}{20*60s}$
30m/s=$\frac{d}{1200s}$⇒d=30m/s * 1200s
d=36000m=36 km
