Question

un biciclist a parcus într-o zi 27 km,a doua zi 1200 dam iar a treia zi 520 hm.Cati km a parcus in total.Va rog!

Answer 1

Prima zi: 27 km
A doua zi: 1200 dam=12 km
A treia zi: 520 hm=52 km
Total: 27 km+12 km+52 km=39 km+52 km= 91 km.

Answer 2

27 km → a parcurs intr-o zi

1 200 dam = ( 1200 : 100 ) km = 12 km → a parcurs a doua zi

520 hm = ( 520 : 10 ) km = 52 km → a parcurs a treia zi

27 km + 12 km + 52 km = 91 km → a parcurs in total
