Question

ПОМОГИТЕ ПРОШУ!ДАМ 14 БАЛОВ! Велосипедист за 4 дня проехал 48 км в первый день он проехал 1/6 этого пути,во второй день - вдвое больше того,что проехал в первый день,а в третий день - три четверти пути,который проехал во второй день.Сколько километров проехал велосипедист в четвёртый день!

Answer 1

48*1/6 = 8 км проехал за 1-й день
8*2=16 км за 2-й
16*3/4= 12км за 3-й

48 - 8 - 16 - 12 = 12 км за 4-й день

Answer 2

Problem Analysis

The cyclist traveled a total distance of 48 km over 4 days. On the first day, the cyclist traveled 1/6 of the total distance. On the second day, the cyclist traveled twice as much as on the first day. On the third day, the cyclist traveled three-quarters of the distance traveled on the second day. We need to calculate the distance traveled on the fourth day.

Solution

To find the distance traveled on the fourth day, we need to subtract the distances traveled on the first three days from the total distance of 48 km.

Let's calculate the distances traveled on each day:

- First day: 1/6 of the total distance = 48 km * (1/6) = 8 km. - Second day: twice the distance traveled on the first day = 8 km * 2 = 16 km. - Third day: three-quarters of the distance traveled on the second day = 16 km * (3/4) = 12 km.

Now, let's calculate the distance traveled on the fourth day:

- Fourth day: total distance - sum of distances traveled on the first three days = 48 km - (8 km + 16 km + 12 km) = 48 km - 36 km = 12 km.

Therefore, the cyclist traveled 12 km on the fourth day.

Answer

The cyclist traveled 12 km on the fourth day.
