Here they have told you the extended amount of time and what that would give you. 8 kilometers=60 minutes, yes? This is a ratio, meaning that you can have mulitiple numbers that mean the same thing. You would, instead of multiplying like you would for a number larger than you're looking for, would simply divide both sides by the same number so that they'll stay even and balanced, the values unchanged. So 8 and 60 have a same multiple, 4. Divide four on both sides to get 2 and 15. 2 would be the number of kilometers you are looking for and 15 would be the number of minutes that Tonya would need to run.
we know that
Tonya runs 8 kilometers in 60 minutes
so
by proportion
Find the time take Tonya to run 2 kilometers
8 60 km min u t es = 2 x km min u t es x ∗ 8 = 60 ∗ 2 x = 60 ∗ 2/8 x = 15 min u t es
therefore
the answer is
** 15 min u t es **
Tonya takes 15 minutes to run 2 kilometers based on her running rate of 8 kilometers in 60 minutes. We calculated this using a proportion based on her speed. The calculation has been verified to ensure it is reasonable.
