Question(4): Find the value of the following in the simplest form: \( 3 \sqrt{2}+2 \sqrt{18}-6 \sqrt{8} \)

For time, \( t \), in hours, \( 0 \leq t \leq 1 \), a bug is crawling at a velocity, \( v \), in meters/hour given by \[ v=\frac{2}{5+t} . \] Use \( \Delta t=0.2 \) to estimate the distance that the bug crawls during this hour. Use left- and right-hand hiemann sums to find an overestimate and an underestimate. Then average the two to get a new estimate. underestimate \( = \) overestimate \( = \) average \( = \) (for each, include units)
