Problema Solution
Jack competes in a long jump for his school track team. At his last meet, he had jumps of 15 feet,8 inches, 16 feet 2 inches, 15 feet 10 inches, and 15 feet 6 inches. What is average length of his jumps at the meet?
Answer provided by our tutors
1 ft = 12 in
15 feet 8 inches = 15*12 + 8 = 188 in
16 feet 2 inches = 16*12 + 2 = 194 in
15 feet 10 inches = 15*12 + 10 = 190 in
5 feet 6 inches = 5*12 + 6 = 66 in
the average length of his jumps at the meet is:
(188 + 194 + 190 + 66)/4 = 159.5 in = 159.5/12 ft = 13 ft 9.5 in
