I spent the evening at Jordan’s house watching him study for the GMAT. I’m not sure I was much help in terms of mechanics and solving strategies, but I provided moral support where I could. Studying for a big test is like anything else: it’s easier when you have a spotter. And it breaks up the monotony when you have someone with whom you can talk through a problem or simply revel in the difficulty. And in that spirit, I figure tonight’s post will be interactive.

1. Point O

2. Scout buys a new car with a fuel efficiency of 25 miles per gallon in the city and 40 miles per gallon on the freeway. On Tuesday, she drives 10 miles in the city and 50 miles on the freeway, what is her total average fuel efficiency for Tuesday?
3. Thanpuii has 5 pieces of wood of varying lengths. The average (arithmetic mean) of the 5 pieces of wood is 124 cm. If the median length is 140 cm, what is the maximum length of the shortest piece of wood?
4. Triangles ABC and BCD are shown in the diagram at right. If line segment AD = 6, what is the length of BC?
5. Solve for x.

Rugby coaches. Notice that Tone on the far right couldn't be bothered to take off his headphones.
Those two I feel confident about. Still working on the others. I think 1 and 2 are both d. but I'm not sure.
