Answer 2

72:8*3=27 км прошли в первый день
(72-27)*40:100=18 км прошли за второй день
72-27-18=27 км осталось пройти

Answer 3

I will answer in detail. The tourists planned to walk 72 km. On the first day of the journey, they walked only 3/8 of the way, on the second day 40% of the remaining way. How many kilometers do the tourists still have to walk?

Let x be the total distance that the tourists planned to walk, then x = 72 km.

On the first day, they walked 3/8 of x, which is 3/8 * 72 = 27 km.

On the second day, they walked 40% of the remaining distance, which is 0.4 * (x - 27) = 0.4 * 45 = 18 km.

The total distance that they walked in two days is 27 + 18 = 45 km.

The remaining distance that they still have to walk is x - 45 = 72 - 45 = 27 km.

Therefore, the tourists still have to walk 27 km.
