Walker, which makes 120 steps per minute, makes the distance from point A to point B 55 minutes. The length of his step is 75cm. How long does this distance go, a boy who will do 110 steps 60 cm long in a minute?

Correct answer:

t =  75 min

Step-by-step explanation:

k1=75 cm m=75:100  m=0.75 m n1=120 1/min  k2=60 cm m=60:100  m=0.6 m n2=110 1/min  s=n1 55 k1=120 55 0.75=4950 m v=n2 k2=110 0.6=66 m/min t=s/v=4950/66=75 min
