Question

за перший день турист пройшов 7,2 км, за другий день - 150% того що за перший. Скільки кілометрів пройшов турист за три дні, якщо за другий день він пройшов 90% того, що за третій?

Answer 1

7.2*1.5=10.8 км во 2 день

10.8 : 0.9=12 км в 3 день

7.2+10.8+12=30 км за три дня 

Answer 2

Calculating the Distance Traveled by the Tourist

To calculate the total distance traveled by the tourist over three days, we can follow these steps:

1. Calculate the distance traveled on the first day. 2. Calculate the distance traveled on the second day. 3. Calculate the distance traveled on the third day. 4. Add up the distances for the three days to find the total distance traveled.

Let's start by calculating the distance traveled on each day.

Distance Traveled on the First Day

The tourist walked 7.2 km on the first day.

Distance Traveled on the Second Day

The tourist walked 150% of the distance covered on the first day on the second day. This can be calculated as: \[ \text{Distance on the second day} = 7.2 \times 1.5 = 10.8 \text{ km} \]

Distance Traveled on the Third Day

To find the distance traveled on the third day, we need to calculate 90% of the distance covered on the third day. \[ \text{Distance on the third day} = 10.8 \times 0.9 = 9.72 \text{ km} \]

Total Distance Traveled

Now, we can find the total distance traveled over the three days by adding up the distances for each day: \[ \text{Total distance} = 7.2 + 10.8 + 9.72 = 27.72 \text{ km} \]

The tourist traveled a total of 27.72 kilometers over three days.
