Question

теплоход проплыл расстояние 100 км со скоростью 12км/ч.за какое время он проплывет это же расстояние если его скорость на 3 км/ч меньшье.

Answer 1

t = S/v, где S – расстояние, v – скорость, t – время 

Answer 2

Calculation of Time Taken to Travel 100 km at a Speed of 12 km/h

To calculate the time taken to travel a distance of 100 km at a speed of 12 km/h, we can use the formula:

Time = Distance / Speed

Substituting the given values:

Time = 100 km / 12 km/h

Calculating the result:

Time = 8.33 hours

Therefore, it would take approximately 8.33 hours to travel a distance of 100 km at a speed of 12 km/h.

Calculation of Time Taken to Travel the Same Distance at a Speed 3 km/h Slower

To calculate the time taken to travel the same distance of 100 km at a speed 3 km/h slower, we can use the same formula:

Time = Distance / Speed

Substituting the given values:

Time = 100 km / (12 km/h - 3 km/h)

Calculating the result:

Time = 100 km / 9 km/h

Time = 11.11 hours

Therefore, it would take approximately 11.11 hours to travel a distance of 100 km at a speed 3 km/h slower than 12 km/h.

Please note that these calculations assume a constant speed throughout the journey and do not account for factors such as acceleration, deceleration, or stops along the way.
