Answer 1

Решение:
72×5=360 км проехал первый день
360÷4=90км/ч скорость второй день

Answer 2

Problem Analysis

The problem states that on the first day, the driver traveled for 5 hours at a speed of 72 km/h. On the second day, the driver traveled the same distance in 4 hours. We need to find the speed at which the driver traveled on the second day.

Solution

To solve this problem, we can use the formula:

Speed = Distance / Time

Let's assume the distance traveled on both days is D.

On the first day: Speed = 72 km/h Time = 5 hours

Using the formula, we can find the distance: D = Speed * Time

On the second day: Time = 4 hours

Using the formula, we can find the speed: Speed = D / Time

Let's calculate the distance and speed.

Calculation

On the first day: Distance = 72 km/h * 5 hours = 360 km

On the second day: Speed = 360 km / 4 hours = 90 km/h

Answer

The driver traveled at a speed of 90 km/h on the second day.
