Question

punctul B imi trebuie urgent ! Va rog frumos

Answer 1

1 km = 20 min 
100 m = 20:10= 2 min
Scoala 2) 1500+500 m= 2000 m
2000 m = 2 km = 20*2= 40 min
40 min + 15 min = 55 min inainte, respectiv ora 8.55.

Scoala 1) 700+600= 1300 m
1300 m= 20 min + (2*3 min)=26 min
26 min+15 min= 41 min inainte, respectiv 9.19min.

Scoala 3) 700+700=1400 m
1400 m = 20 min + (2*4 min) = 28 min
28 min +15 min = 43 min inainte, respectiv  9.17 min 

Scoala 4) 400+700 = 1100 m
1100 m = 20 min +2 min = 22 min
22 min +15 min = 37 min inainte,   respectiv  9.23 min.
