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

b. 2 and 4

step-by-step explanation:

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
