Question

Скорый поезд за 3часа преодолел расстояние360км.С какой двигался поезд,если она была постоянной. Бригада дорожных рабочих за 3часа работы расчистили 360кв.м.дорожного полотна

Answer 1

1) 360:3=120(км/ч).

1)360:3=120 (км/ч).

Answer 2

360/3=120 км/ч скорость
360/3 =120 кв м за 1 час

Answer 3

Train Speed Calculation

To calculate the speed of the train, we can use the formula:

Speed = Distance / Time

Given that the train covered a distance of 360 km in 3 hours, we can calculate its speed as follows:

Speed = 360 km / 3 hours

Speed = 120 km/h

Therefore, the train was moving at a speed of 120 km/h.

Road Workers' Efficiency

The efficiency of the road workers can be calculated using the formula:

Efficiency = Work Done / Time Taken

Given that the road workers cleared 360 square meters of road in 3 hours, we can calculate their efficiency as follows:

Efficiency = 360 sq.m / 3 hours

Efficiency = 120 sq.m/h

Therefore, the road workers' efficiency was 120 square meters per hour.
