In two days the tourist covered 27.4 km of the way. On the second day he covered 2.3 km less than on the first day. How many kilometers did the tourist walk on the first day?

Let us denote by d km the length of the tourist’s path on the 1st day, then (d – 2.3) km will be the tourist’s path on the 2nd day.

d + d – 2.3 = 27.4;

2d = 27.4 + 2.3;

2d = 29.7;

d = 29.7 / 2;

d = 14.85 (km) – the length of the tourist’s path on the 1st day.

Answer: 14.85 km.
