Well the variance is how close or far the points are from the mean.. so if it is a large variance then the sample with be very spread out. If your variance is large then your standard deviation is also large.
1058+44.50 =1102.5
1102.5-1000=102.5
102.5 is your anwser
Boy record = 25 feet 8 inches
Girl record = 19 feet 19 inches
Boy record / Girl record = 25 feet 8 inches / 19 feet 19 inches
Change the feet into inches
1 feet = 12 inches
25 feet = 25* 12 = 300 inches + 8 inches = 308 inches
19 feet = 19 * 12= 228 inches + 19 inches = 247 inches
Boy record / Girl record = 308 inches / 247 inches
Boy record / Girl record = 1.246 inches
Boy record = 1.246 Girl record
So
it is 1.246 times greater than girls record.
