Question

Слон пробегает 180м за 15 с, а лев может пробежать такое же расстояние за 9 с. За какое время слон пробежит 720 м? За какое время лев пробежит 360 м ?

Answer 1

1)180:15=12 м/с скорость слона

2)720:12=60 с за это время слон пробежит 720 м

3)180:9=20 м/с скорость льва

4)360:20=18 с за такое время лев пробежит 360 м

Answer 2

Calculation for the Elephant:

To find out how long it will take for the elephant to run 720 meters, we can use the formula:

Time = Distance / Speed

Given that the elephant can run 180 meters in 15 seconds, we can calculate its speed:

Speed = Distance / Time = 180 meters / 15 seconds = 12 meters per second [[1]].

Now, we can use the speed to calculate the time it will take for the elephant to run 720 meters:

Time = Distance / Speed = 720 meters / 12 meters per second = 60 seconds.

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

Calculation for the Lion:

Similarly, to find out how long it will take for the lion to run 360 meters, we can use the same formula:

Time = Distance / Speed

Given that the lion can run the same distance as the elephant (180 meters) in 9 seconds, we can calculate its speed:

Speed = Distance / Time = 180 meters / 9 seconds = 20 meters per second [[2]].

Now, we can use the speed to calculate the time it will take for the lion to run 360 meters:

Time = Distance / Speed = 360 meters / 20 meters per second = 18 seconds.

Therefore, it will take the lion 18 seconds to run 360 meters.
