Three-day trip

The cyclist on three-day trip travel 30% of the total route on the first day, 3/5 of the rest on the second day, and 35 km on the third day. How many kilometers did cyclists travel each day, and how many?

Correct answer:

a =  37.5 km
b =  52.5 km
c =  35 km
s =  125 km

Step-by-step explanation:

c=35 km q=30%=10030=103=0.3  a + b + c = s a = q  s b = 53   (sa)  q s+53 (sq s)+c=s 0.3 s+53 (s0.3 s)+35=s  0.3 s+3/5 (s0.3 s)+35=s  1.4s=175  s=1.4175=125  s=125  a=q s=0.3 125=275 km=37.5 km
b=53 (sa)=53 (12537.5)=2105 km=52.5 km
