Question

230. Из Лениграда в Москву в 9 ч дня вышла грузовая машина со скоростью 48 км/ч. В 10 ч из Москвы в Ленин- град вышла легковая машина со скоростью 82 км/ч. Какое расстояние было между машинами в 12 ч того же Дня, если между Москвой и Ленинградом расстояние 650 км?​

Answer 1

Ответ:

342 км

Пошаговое объяснение:

грузовая машина прошла 48*3 = 144 км

легковая 82*2 = 164 км.

144+164 = 308 км - пройдено

Расстояние 650 -308 = 342 км.

Answer 2

Given Information

A cargo truck left from Leningrad to Moscow at 9:00 AM with a speed of 48 km/h. At 10:00 AM, a passenger car left from Moscow to Leningrad with a speed of 82 km/h. The distance between Moscow and Leningrad is 650 km.

Calculating the Distance Between the Vehicles

To find the distance between the vehicles at 12:00 PM, we can use the formula: Distance = Speed * Time

The cargo truck traveled for 3 hours (from 9:00 AM to 12:00 PM), covering a distance of: 48 km/h * 3 h = 144 km The passenger car traveled for 2 hours (from 10:00 AM to 12:00 PM), covering a distance of: 82 km/h * 2 h = 164 km The total distance between the vehicles at 12:00 PM is the sum of the distances covered by each vehicle: 144 km (distance covered by the cargo truck) + 164 km (distance covered by the passenger car) = 308 km

Conclusion

Therefore, at 12:00 PM on the same day, the distance between the cargo truck and the passenger car was 308 km.
