Hello,

742/27 (ft)

Step-by-step explanation:

h_1=14\\\\h_2=\dfrac{14}{3} \\\\h_3=\dfrac{14}{9} \\\\h_4=\dfrac{14}{27} \\\\

d=14+2*\dfrac{14}{3} +2*\dfrac{14}{9} +2*\dfrac{14}{27} \\=14*(1+\dfrac{1}{3}+\dfrac{2}{9} +\dfrac{2}{27} )\\=14*\dfrac{53}{27} \\=\dfrac{742}{27} \\

I'm pretty sure it's 1 cup of water

You need 2 cups of pancake mix more than water so if you have 3 cups of pancake mix then you'd need 1 cup of water.

6 cups of mix = 4 cups of water

the cups of the mix is are 2 more cups than the water

3 cups of mix = 1 cup of water

I hope that helps and good luck! :)

RideAnS [48]

Answer:

7.2 km

Step-by-step explanation:

Given that:

Hours taken = 2 hours

Walk rate = 1 m/s

Distance = Speed * time

Time taken in seconds = 2 * 60 * 60 = 7200 s

Hence,

Distance = 1 m/s * 7200s

Distance = 7200 meters

Distance in km = 7200 / 1000 = 7.2 km
