Question

60 km/h cat parcurge in 3 h si 10 min

Answer 1

Răspuns: 190 km

Explicație pas cu pas:

1 ora = 60 minute

viteza = distanta : timp

v = d / t

d = vt

     v = 60 km / h = 60 km / 60 min = 1 km / minut

     t = 3 ore 10 min = 3 x 60 + 10 = 190 minute

d = vt = 1 km/min x 190 min = 190 km

Answer 2

t=3h10min=3×60+10min=180+10min=190min

$v=\frac{60km}{h} =\frac{60km}{60min}=1km/min$

$v=\frac{d}{t}$

$\frac{1km}{1min} =\frac{d}{190min}$

d=1×190:1=190km
