Rudolpho takes 12 minutes to run 6 times around a 400 meter track. assuming he runs at a constant speed, how long does it take to run 1 kilometer?

5 minutes to run 1 km.

Step-by-step explanation:

If he runs 6 times around a 400m track, then he has run 6x400m= 2400m.  This takes him 12 minutes.  1km is 1000m.  So, he runs 2.4 km in 12 minutes.  To run 1km, we divide 12 by 2.4. 12/2.4= 5 minutes to run 1 km.

hope this helps.

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5
