Question

Турист проехал 90км за 2 часа . он проехал на 1,6км больше чем в первый час.Сколько он проехал во второй час?

Answer 1

90 км+1,6 км=91,6 км (проехал бы турист. если бы в 1-й час проехал бы столько же, сколько и во второй) (попросту - удвоенное количество километров за второй час)
91,6 км:2=45,8 км
Ответ: во второй час турист проехал 45,8 км

Answer 2

Problem Analysis

A tourist traveled 90 km in 2 hours. In the second hour, they traveled 1.6 km more than in the first hour. We need to determine how far the tourist traveled in the second hour.

Solution

Let's break down the information given:

- Total distance traveled: 90 km - Total time taken: 2 hours - Distance traveled in the first hour: x km - Distance traveled in the second hour: x + 1.6 km

To find the distance traveled in the second hour, we can use the following equation:

Distance traveled in the first hour + Distance traveled in the second hour = Total distance traveled

x + (x + 1.6) = 90

Simplifying the equation:

2x + 1.6 = 90

Subtracting 1.6 from both sides:

2x = 88.4

Dividing both sides by 2:

x = 44.2

Therefore, the distance traveled in the first hour is 44.2 km.

To find the distance traveled in the second hour, we can substitute the value of x into the equation:

Distance traveled in the second hour = x + 1.6 = 44.2 + 1.6 = 45.8 km

Therefore, the tourist traveled 45.8 km in the second hour.

Answer

The tourist traveled 45.8 km in the second hour.
