81 servings. I found this by making a ratio:
24 c            108 c
-------     =    -------
18 ser            x
I then cross multiplied to get the equation: 24x=1,944. I solved this equation to find x, the number of servings in 108 cups, which was 81. 

I remember doing this back in elementary school. I had a hard time with it too!

The 888 mile trip to the ranch took three times as long as the 280 mile trip to the ocean because the speed was 4 mph less than
ziro4ka [17]

Alright, lets get started.

Suppose the speed to the ranch = x mph

So, speed to the ocean will be = (x-4) mph (because the speed was 4 mph less than the speed to the ranch)

Distance to the ranch = 888 miles

time moving to the ranch = \frac{distance}{speed}

time moving to the ranch = \frac{888}{x}

time moving to the ocean = \frac{280}{x-4}

As per given in question, the 888 mile trip to the ranch took three times as long as the 280 mile trip to the ocean , means

\frac{888}{x} = 3 * \frac{280}{x-4}

\frac{888}{x}= \frac{840}{x-4}

Corss multiplying

888 (x-4) = 840 x

888 x - 3552 = 840 x

48 x = 3552

x=74

Hence speed to ranch = 74 mph

Hence speed to ocean = 74 - 4 = 70 mph

time for trip to ranch = \frac{888}{74}  = 12 hrs

time for trip to ocean = \frac{280}{70} = 4 hrs

So, speed to ranch is 74 mph and trip time is 12 hrs and speed to ocean is 70mph and time is 4 hrs.

Hope it will help :)
