Question

In 1935 american athlete jesse owens set a world record for the long jump by jumping 26ft 8 1/6 in.In 1960 ralph boston set a new world record by jumping 26ft 11 1/4 in. How much longer was ralph bostons jump?

Answer 1

Step 1

Subtract 26 ft 8 1/6 in from 26 ft 11 1/4 in

(26 ft 11 1/4 in)-(26 ft 8 1/6 in)=11 1/4 in-8 1/16 in

we know that

11 1/4=(11*4+1)/4=45/4

8 1/16=(8*16+1)/16=129/16

so

11 1/4 in-8 1/16 in=(45/4)-(129/16)

=(4*45-129)/16

=51/16 in--------> 3 3/16 in

therefore

the answer is

3 3/16 in
