Let the line L be defined by x=t+1 y = 2t+1 z=3t+1 (a) Write a formula for the distance between the point (1,1,0) and an arbitrary point on the line L. (b) Farmer Bob was walking near a golf course when a golf ball comes whizzing by. Suppose the golf ball is following the line L (with units measured in inches) and t is measuring how many minutes since the golfer swung at the ball. Find out how close the ball came to hitting Farmer Bob, and at what time t that happened.

1. Let the line L be defined by
x=t+1 y = 2t +12=3t+1
(a) Write a formula for the distance between the point (1,1,0) and an arbitrary point
on the line L.
(b) Farmer Bob was walking near a golf course when a golf ball comes whizzing by.
Suppose the golf ball is following the line L (with units measured in inches) and t
is measuring how many minutes since the golfer swung at the ball. Find out how
close the ball came to hitting Farmer Bob, and at what time t that happened.
