In the diagram, the base of the tower is at point H, and the top of the tower is at point F. If the distance from the base of th
e tower to point G is 7x feet and the distance from the base of the tower to point E is 6x + 12 feet, find GE, the distance across the lake. A. 84 feet
B. 94 feet
C. 168 feet
D. 186 feet

In the given problem the best hint that is given for getting to the answer is that Evan's family drove at the same speed each day. Then On the first day the speed of the car = Distance/time = 300/6 = 50 miles/hour Then for calculating the distance traveled on the third day = speed * time = 50 * 3 = 150 miles Then on the third day they arrived at the park by driving 150 miles in 3 hours. So the correct option is option "C".
