Question

Мотоцикліст їхав 5 год з однаковою швидкістю.До обіду він проїхав 140 км, а після обіду_ 110 км. Скільки годин проїхав мотоцикліст до обіду?Будь ласка з поясненням

Answer 1

!)140+110=250(км)-увесь шлях
2)250\5=50(км\год)-швидкість мотоцикліста
3)140\50=2.8(год)
ВідповідьЖдо обіду мотоцикліст подолав шлях за 2.8 год

Answer 2

Calculation of the Time the Motorcyclist Traveled Before Noon

To calculate the time the motorcyclist traveled before noon, we need to determine the speed at which the motorcyclist was traveling. We can do this by dividing the total distance traveled before noon by the time it took to cover that distance.

The motorcyclist traveled 140 km before noon. Let's assume the speed at which the motorcyclist was traveling is x km/h.

The time it took to cover the distance before noon can be calculated using the formula:

Time = Distance / Speed

Substituting the given values, we have:

5 hours = 140 km / x km/h

To find the value of x, we can rearrange the equation:

x km/h = 140 km / 5 hours

Simplifying the equation, we find:

x km/h = 28 km/h

Therefore, the motorcyclist was traveling at a speed of 28 km/h before noon.

Calculation of the Time the Motorcyclist Traveled After Noon

To calculate the time the motorcyclist traveled after noon, we can use the same formula:

Time = Distance / Speed

The motorcyclist traveled 110 km after noon. Let's assume the speed at which the motorcyclist was traveling is still x km/h.

Substituting the given values, we have:

Time = 110 km / x km/h

Since we already determined that the speed before noon was 28 km/h, we can substitute that value into the equation:

Time = 110 km / 28 km/h

Simplifying the equation, we find:

Time = 3.93 hours

Therefore, the motorcyclist traveled for approximately 3.93 hours after noon.

Calculation of the Total Time Traveled by the Motorcyclist

To calculate the total time traveled by the motorcyclist, we can add the time traveled before noon and the time traveled after noon:

Total Time = Time Before Noon + Time After Noon

Substituting the given values, we have:

Total Time = 5 hours + 3.93 hours

Simplifying the equation, we find:

Total Time = 8.93 hours

Therefore, the motorcyclist traveled for approximately 8.93 hours in total.

In summary, the motorcyclist traveled for approximately 5 hours before noon and approximately 3.93 hours after noon, with a total travel time of approximately 8.93 hours.
