Sisters

Sisters Hanka and Vera go mostly to their grandmother by bicycle. Journey took Hanka 30 minutes and Vera 20 minutes. How long will Vera catch up with Hanka when she starts from home five minutes later than Hanka?

Correct answer:

t =  10 min

Step-by-step explanation:

v1=30s v2=20s v1(t+5)=v2t 30s(t+5)=20st (t+5)/30=t/20 t=10 min

(t+5)/30 = t/20

t = 10


t = 10/1 = 10

t = 10
