Question

Слон пробегает 180 метров за 15 секунд а лев может пробежать такое же расстояние за 9 с.За какое время слон пробежит 720м за какое время лев пробежит 360м?Без иксов решите.Пожалуйсто!

Answer 1

1) 720 : 180=4
2)4*15=60поробежит слон.
3)360:180=2
4)2*9=18пробежит лев.

Answer 2

180/15=12 м пробегает слон за 1 секунду
720/12=60 с или 1 минуту пробегает слон 720 м
180/9=20 м. пробегает лев за 1 секунду
360/20=18 с за столько пробегает лев 360 м

Answer 3

Problem Analysis

We are given that an elephant can run 180 meters in 15 seconds, and a lion can run the same distance in 9 seconds. We need to find out how long it will take for the elephant to run 720 meters and for the lion to run 360 meters.

Elephant's Time Calculation

To find out how long it will take for the elephant to run 720 meters, we can set up a proportion using the given information: 180 meters / 15 seconds = 720 meters / x seconds

To solve this proportion, we can cross-multiply and then divide: 180 * x = 15 * 720 x = (15 * 720) / 180

Let's calculate the time it will take for the elephant to run 720 meters: x = (15 * 720) / 180 = 60 seconds

Therefore, it will take the elephant 60 seconds to run 720 meters.

Lion's Time Calculation

Similarly, to find out how long it will take for the lion to run 360 meters, we can set up a proportion using the given information: 180 meters / 15 seconds = 360 meters / x seconds

Again, we can cross-multiply and then divide to solve the proportion: 180 * x = 15 * 360 x = (15 * 360) / 180

Let's calculate the time it will take for the lion to run 360 meters: x = (15 * 360) / 180 = 30 seconds

Therefore, it will take the lion 30 seconds to run 360 meters.

Conclusion

To summarize: - The elephant will take 60 seconds to run 720 meters. - The lion will take 30 seconds to run 360 meters.
