To make getting to bwi easier, we are going to use a shuttle service. due to an accident on i-195, we will get on the baltimore beltway (i-695) at exit 12b, wilkins avenue and take it to exit 7, the baltimore washington parkway (md 295). assuming the beltway is a perfect circle with a radius of 7.79 miles, and the angle between exit 7 and exit 12b is 0.513 radians: a. find the distance we traveled on the beltway. (draw relevant diagram.) b. if our average driving speed was 59 mph, how long did it take us to travel from exit 7 to exit 12b?
