Question

За какое время автомобиль пройдет из пункта А в пункт Б двигаясь со скоростью 54 км/ч,а назад со скоростью 36 км/ч если расстояние между А и Б 216 км?

Answer 1

216:54=4(часа)-в пункт В
216:36=6(часов)- в пункт А
6+4=10(часов)-туда обратно

Answer 2

Calculating Time Taken to Travel

To calculate the time it takes for the car to travel from point A to point B and back, we can use the formula: \[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \]

Given: - Speed from A to B = 54 km/h - Speed from B to A = 36 km/h - Distance between A and B = 216 km

Using the formula, we can calculate the time taken for each leg of the journey.

1. Time taken from A to B: \[ \text{Time} = \frac{216 \text{ km}}{54 \text{ km/h}} = 4 \text{ hours} \]

2. Time taken from B to A: \[ \text{Time} = \frac{216 \text{ km}}{36 \text{ km/h}} = 6 \text{ hours} \]

Therefore, the total time taken for the round trip is 4 hours from A to B and 6 hours from B to A, totaling 10 hours.
