Bob and Wendy planned to walk from their home to a restaurant for dinner together. However, Bob was delayed at work, and Wendy left for the restaurant before Bob did. If the restaurant is 3 miles from their home and Bob left for the restaurant a half-hour after Wendy did, how long did Wendy have to wait for Bob at the restaurant?
(1) Wendy walked at a constant pace of 4 miles per hour
(2) Bob walked at a constant pace of 1 mile per hour faster than Wendy.
The OA is [spoiler] C . It would take both conditions. The first condition doesnt give us anything about Bob, so it's insufficient. At first I thought the second condition would be sufficient as well but then I thought about it, what if Wendy walked at the speed of light? Both she and Bob would get there in 1 nano second. Wendy could also walk at the speed of the the earth's rotation around the sun and get there much later... So we don't know the difference. [/spoiler].
good logic? haha
