1 yard is 36 inches, 1 foot is 12 inches.
Part A:
Her first jump is (3*36)+(12*2)+8= 140 inches
Her second jump is (2*36)+(12)+10= 94 inches
Her first jump is 46 inches longer (140-94).
Part B:
The total length of the two jumps: 140+94 = 234 inches
Part C:
The WR for women's jump is (24*12)+8= 296 inches
296-140 = 156 inches.
156/36= 4.3 yards
