Question

Почтовый голубь должен доставить донесение на расстояние 130 км.Скорость голубя 50 км/ч..Успеет ли голубь доставить это донесение за 2 часа или за 3 часа. ВСЕМ СПАСИБО!!!

Answer 1

За 2 часа пролетит 2*50 = 100 км - не успеет (100<130).
За 3 часа пролетит 3*50 = 150 км - успеет (150>130).

Answer 2

Delivery Time Calculation for the Pigeon

To determine whether the pigeon will be able to deliver the message within 2 or 3 hours, we need to calculate the time it will take for the pigeon to cover the distance of 130 km at a speed of 50 km/h.

The formula to calculate time is:

Time = Distance / Speed

Let's calculate the time for both scenarios:

1. Delivery in 2 hours: - Time = 130 km / 50 km/h - Time = 2.6 hours

2. Delivery in 3 hours: - Time = 130 km / 50 km/h - Time = 2.6 hours

Based on the calculations, it will take the pigeon approximately 2.6 hours to cover the distance of 130 km, regardless of whether the target delivery time is 2 or 3 hours.

Therefore, the pigeon will not be able to deliver the message within 2 hours, but it will be able to deliver it within 3 hours.

Please note that these calculations assume a constant speed for the pigeon throughout the entire journey and do not take into account factors such as wind speed or fatigue.
