Question 23068: Please help. I'm trying to assist my friend's daughter and I'm very rusty.

A river is 3,100 meters wide
There is a bridge that spans the river
1/10 of the bridge lies on one side of the river
1/8 of the bridge lies on the other side of the river
How long is the bridge

Try some WD-40 for your rust problem. (lol)
The bridge is 3,100m + (1/10)(3,100m) + (1/8)(3,100m) = 3,100 + 310 + 387.5 = 3797.5 meters long.
