Problem $4$: Determine the breaking efficiency $($fill in the blanks$)$

A driver is traveling at $80m\frac{i}{h}$ down a $3\%$ grade on good, wet pavement. An accident investigation team noted that breaking skid marks started $410$ ft before a parked car was hit at an estimated $45m\frac{i}{h}.$ lgnoring air resistance, and using theoretical stopping distance, what was the breaking efficiency of the car? Round all answers to two decimal places, unless otherwise specified. Pay close attention to the units.

$frl=($round to three decimals$)$

$b=-10$ points
