Answer 1

Ответ:

Пошаговое объяснение:

40×1/4=40:4=10км в 1 день

40×2/5=40:5×2=16км во 2 день

40-(10+16)=14км в 3 день

Answer 2

Ответ:

1) 2,5+1,4=3,9

2) 40-3,9=0, 1

ответ :0,1

Answer 3

Calculation of the Distance Covered by the Tourist

To calculate the distance covered by the tourist on the third day, we need to subtract the distances covered on the first and second days from the total distance covered in three days.

Let's break down the given information:

- Total distance covered in three days: 40 km - Distance covered on the first day: 1.4 times the total distance - Distance covered on the second day: 2.5 times the total distance

To find the distance covered on the third day, we can use the following equation:

Total distance = Distance on the first day + Distance on the second day + Distance on the third day

Let's solve for the distance on the third day:

40 km = 1.4 x Total distance + 2.5 x Total distance + Distance on the third day

Simplifying the equation:

40 km = 3.9 x Total distance + Distance on the third day

To isolate the distance on the third day, we subtract the total distance multiplied by 3.9 from both sides of the equation:

Distance on the third day = 40 km - 3.9 x Total distance

Now, let's substitute the value of the total distance covered in three days:

Distance on the third day = 40 km - 3.9 x 40 km

Calculating the result:

Distance on the third day = 40 km - 156 km

Distance on the third day = -116 km

Based on the given information, the result is a negative distance of -116 km for the third day. However, it is not possible to cover a negative distance. Therefore, it seems there might be an error in the given information or calculations.
