Ok clearly my math is terrible, but i don't understand your explanation, still.

Hmmm, d = rt + rt
21 = 12*t + 8*(2-t), clarify what doesn't make sense so I can help you with that part.

. + ( + ) x2 = (.)(.)

De-Ting · Jan 19, 2011

(.)^2 = [.][.]

MattAY · Jan 19, 2011

[.][.] + air pump = ( o )( o )

The time at 12 mph is t. The time at 8 mph is 2 hours minus t.

Bretimus_v2 · Jan 19, 2011

Since you know he took 2 hrs you have one set, t, and the other is simply the remainder of the 2 hours, 2-t.
