Car

Car travels 1/3 of the trip on the first day, second day 2/5 of the trip and left even 340 km for next days. How long is the trip?

Result

x =  1275 km

Solution:

x13x25x=340 x(11325)=340 x=34011325 x=1275  km x-\dfrac{ 1}{ 3} x - \dfrac{ 2}{ 5} x = 340 \ \\ x(1 - \dfrac{ 1}{ 3} - \dfrac{ 2}{ 5}) = 340 \ \\ x = \dfrac{ 340} {1 - \dfrac{ 1}{ 3} - \dfrac{ 2}{ 5}} \ \\ x = 1275 \ \text { km }
