Q: Passage: After their big road win in Washington, the Eagles hosted the winless Miami Dolphins at muddy Lincoln Financial Field and won 17-7. The offenses struggled in the first quarter, and the first points would actually come via special teams in the second quarter, when Ted Ginn Jr. returned a punt 87 yards to paydirt for Miami. Later in the quarter, McNabb, who had already thrown two interceptions, was hit as he threw, spraining his ankle. David Akers came on to make a 34-yard field goal, and McNabb left the game. A. J. Feeley was spun up to play quarterback, but threw an interception of his own on his first drive. In the third quarter, Correll Buckhalter took the ball in from eight yards out for the go-ahead touchdown, making it 10-7. Feeley, after some helpful runs from running back Brian Westbrook, connected with receiver Jason Avant to increase the lead. The defense played a strong second half, and Westbrook carried seven times on the final drive, which killed the final 6:40 of the game. Without McNabb, Andy Reid leaned hard on Westbrook, who shattered his career-high with 32 carries, while picking up 148 yards. McNabb's post-game x-rays were negative. The win marked the first time Philadelphia had won consecutive games all season, as well as allowing them to reach .500 and remain in the playoff hunt in the NFC. 
Question: How many yards per carry did Brian Westbrook average during this game? 
Answer type: Number 

A: 4.62.
