Question

На путь из пункта А в пункт В автомобиль затратил 1 целую и 2/3часа а на обратный путь на 10 минут больше.Определите скорость автомобиля в каждом направлении если расстояние от А до В равно 110 км помогите!!! СРОЧНО НАДО

Answer 1

1целая 2/3 часа= 100 /60часа
1)110:100/60 = 66км/ч -скорость из А в В
2)110: 110/60 =60 км/ч- скорость из В-А

Answer 2

Calculation of Speed

To determine the speed of the car in each direction, we can use the formula:

Speed = Distance / Time

Given that the distance from point A to point B is 110 km, and the car took 1 hour and 2/3 hours (or 5/3 hours) to travel from point A to point B, we can calculate the speed in that direction:

Speed from A to B = 110 km / (5/3 hours)

To calculate the speed from point B back to point A, we know that it took 10 minutes (or 1/6 hours) longer than the initial journey. Therefore, the time for the return journey is:

Time for return journey = 5/3 hours + 1/6 hours

Now we can calculate the speed from point B back to point A:

Speed from B to A = 110 km / (5/3 hours + 1/6 hours)

Let's calculate the speeds in each direction:

Speed from A to B = 110 km / (5/3 hours) = 66 km/h

Speed from B to A = 110 km / (5/3 hours + 1/6 hours) = 55 km/h

Therefore, the speed of the car from point A to point B is 66 km/h, and the speed from point B back to point A is 55 km/h.
