Oldřich ran out of the house at 7.00 at 10 km / h. After 3 minutes, Jaroslav also ran at 12 km / h. A) what time did Jaroslav Oldřich finish? B) how many km did each run?


t = 7:18 hh:mm Wrong answer
s =  73 km

Step-by-step explanation:

v1=10 km/h v2=12 km/h T=3 min h=3:60  h=0.05 h  s1=s2  v1 x=v2 (xT) 10 x=12 (x0.05)  2x=0.6  x=20.6=0.3  x=103=0.3  t=7.00+x=7.00+0.3=7.3=7:18 hh:mm
s=v1 t=v1 1073=10 7.3=73 km
