Question

В таблицах даны скорости вороны 250 м.мин и комары 90 см.с , льва 75 км.ч и кенгуру 80 км.ч............ определите, какое расстояние пролетит ворона за 2 мин., а комар за 3 сек.какой путь преодолеет лев за 4 ч., а кенгуру за 30 мин...извените пожалуйста)))))

Answer 1

250 х 2 = 500 м -ворона
90 х 3 = 270 см = 2м70см - комар
75 х 4 = 300 км - лев
80 : 2 = 40 км - кенгуру

Answer 2

250*2=500 м пролетит ворона за 2 мин
90*3=270 см пролетит комар за 3 сек
75*4=300 км преодолеет лев за 4 часа
80:2=40 км преодолеет кенгуру за 30 мин

Answer 3

Calculation of Distances

To calculate the distances traveled by the crow and the mosquito, as well as the lion and the kangaroo, we can use the formula:

Distance = Speed × Time

Let's calculate each distance step by step:

1. Distance traveled by the crow in 2 minutes: - Speed of the crow: 250 m/min - Time: 2 minutes - Distance = 250 m/min × 2 min = 500 meters

2. Distance traveled by the mosquito in 3 seconds: - Speed of the mosquito: 90 cm/s - Time: 3 seconds - Convert cm to meters: 90 cm = 0.9 meters - Distance = 0.9 m/s × 3 s = 2.7 meters

3. Distance traveled by the lion in 4 hours: - Speed of the lion: 75 km/h - Time: 4 hours - Convert km to meters: 75 km = 75,000 meters - Convert hours to seconds: 4 hours = 14,400 seconds - Distance = 75,000 m/14,400 s = 5.21 meters per second - Distance = 5.21 m/s × 14,400 s = 75,024 meters

4. Distance traveled by the kangaroo in 30 minutes: - Speed of the kangaroo: 80 km/h - Time: 30 minutes - Convert km to meters: 80 km = 80,000 meters - Convert minutes to seconds: 30 minutes = 1,800 seconds - Distance = 80,000 m/1,800 s = 44.44 meters per second - Distance = 44.44 m/s × 1,800 s = 80,000 meters

Therefore, the distances traveled are as follows:

- The crow will fly 500 meters in 2 minutes. - The mosquito will fly 2.7 meters in 3 seconds. - The lion will cover 75,024 meters in 4 hours. - The kangaroo will cover 80,000 meters in 30 minutes.

Please note that these calculations assume constant speeds for the animals throughout their respective journeys.
