The bath

Dad poured 50 liters of water at 60°C into the tub. How much cold water must be added at 10°C to obtain a bath that has a temperature of 40°C?

Correct result:

V2 =  33.3333 l

Solution:

V1=50 l t1=60t2=10t=40   V1 t1+V2 t2=(V1+V2) t 50 60+V2 10=(50+V2) 40  30V2=1000  V2=100333.333333=33.3333 l
