Question

Шофер ехал с определенной скорастью 7 часа и токой же скорастью 3часа и проехал расстояние 640 км .сколько км проехал шофер в первые 7 часа

Answer 1

1) 7 + 3 = 10 (ч) - всего
2) 640 : 10 = 64 (км/ч) - скорость
3) 64 * 7 = 448 (км) - за 7 часов

Answer 2

7+3=10часов шофер был в пути
640:10=64км/час скорость
64*7=448км

Answer 3

Calculating Distance Traveled by the Driver

To calculate the distance traveled by the driver in the first 7 hours, we can use the formula: distance = speed × time.

Given that the driver traveled at a certain speed for 7 hours and the same speed for 3 hours, and covered a total distance of 640 km, we can calculate the distance traveled in the first 7 hours.

Using the formula, we can calculate the speed of the driver: - Speed = Distance / Time

First, let's calculate the speed of the driver: - Speed = 640 km / 7 hours - Speed = 91.43 km/h Now, we can calculate the distance traveled in the first 7 hours: - Distance = Speed × Time - Distance = 91.43 km/h × 7 hours - Distance = 640 km So, the driver traveled 640 km in the first 7 hours.
