Question

Туристы прошли 69 км.первы3 часа они шли со скоростью 5 км/ч.Остальную часть пути прошли за 6 часов.С какой скоростью прошли туристы остальную часть пути?

Answer 1

1) 3*5=15(км) туристы прошли за первые три часа.

2) 69-15=54(км) туристы прошли за шесть часов.

3) 54:6=9(км/ч)

Ответ: оставшуюся часть туристы прошли со скоростью 9 км/ч.

Answer 2

5*3=15 (км) - за первые три часа
69-15=54 (км) - прошли туристы за 6 часов
54/6=9 (км/ч) - скорость туристов на остальном части пути

Answer 3

Calculation of the Total Distance Traveled

To find the speed at which the tourists covered the remaining part of the journey, we first need to calculate the total distance traveled by the tourists.

The tourists walked for 3 hours at a speed of 5 km/h. Therefore, the distance covered in the first 3 hours is:

Distance1 = Speed1 × Time1 = 5 km/h × 3 h = 15 km.

The remaining part of the journey was covered in 6 hours. Let's denote the speed at which the tourists covered this part as Speed2. The distance covered in the remaining 6 hours is:

Distance2 = Speed2 × Time2 = Speed2 × 6 h.

The total distance traveled by the tourists is the sum of Distance1 and Distance2:

Total Distance = Distance1 + Distance2 = 15 km + (Speed2 × 6 h).

Calculation of the Speed for the Remaining Part of the Journey

To find the speed at which the tourists covered the remaining part of the journey, we need to solve the equation for the total distance:

Total Distance = 69 km.

Substituting the values, we have:

69 km = 15 km + (Speed2 × 6 h).

To isolate Speed2, we can rearrange the equation:

Speed2 × 6 h = 69 km - 15 km.

Simplifying the equation:

Speed2 × 6 h = 54 km.

Finally, we can solve for Speed2:

Speed2 = 54 km / 6 h = 9 km/h.

Therefore, the tourists covered the remaining part of the journey at a speed of 9 km/h.
