Question

1. [40000+40ori5000]dg egalhg?
2.Calculeaza in secunde 2ore+10min+30s
3.Calculeaza cate ore are luna decembrie
4.Calculeaza viteza medie de deplasare a unui automabil care trabate 180km in tri ore si 10 min

Answer 1

1. (40000+40x5000)dg =240000 dg
2. 2 ore =7200s
   10 min = 600s
    7200s+600s+30s=7830s
3. 31(zile) x 24(ore/zi) =744 ore
4. v= delta d supra delta t
adica 180km supra 3h10min
*Notam "supra" cu "/"
v= 180km/180+10min
v= 180000 m/ 11400 s
v= 1800m/114 s
v= 15,90 m/s
