The formula S= 30fd can be used to estimate the speed, s, in miles hour that a car is traveling when it goes into a skid, where f is the coefficient of
friction and d is the length of the skid marks in feet.
per
On a busy highway with a speed limit of 70 mi/h, a truck ahead of Verna jackknifes
across the road. Verna skids to a stop 10 ft short of the truck. Her skid marks
measure 260 ft. Was Verna speeding?
No; her speed was only 63 mi/h.
Yes: her speed was 73.9 mi/h.
Yes: her speed was 75.3 mi/h
No: her speed was 70 mi/h

Add the fractions, and simply the result to lowest terms. 2/3 + 2/7= ?
