Lance can run 100 meters in 15 seconds. If he maintains that same speed, how many minutes would it take him to run a kilometer?

2mins and 30 secs

Step-by-step explanation:

100m in 15 secs

100m/15secs

1000m = 1 km

multiply the ratio by 10 to make the 100meters 1000, because that is how many meters are in a kilometer

10(100m/15secs)

1000m/150secs

So it takes 150 seconds to run 1 kilometer or 1000 meters

150 seconds is also

2mins and 30 secs

the first one

step-by-step explanation:

just id the test.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
