Question

Viteza este de 15 intregi 2 pe 3 km/h iar distanta e de 4,7 km. CIT VĂ FI TIMPUL?

Answer 1

v = $15 \frac{2}{3} km/h$
d = 4,7 km
v = $\frac{d}{t}$ ⇔ $15 \frac{2}{3} = \frac{4,7km}{t}$ ⇔ $15 \frac{2}{3} *t=4,7$ ⇔ $t= \frac{4,7}{ \frac{47}{3} }= 4,7* \frac{3}{47} = \frac{14,1}{47} =0,3$ (ore).
