Question

Here are the Indian Records and World Records for some jumps.

Sports	World Record	Indian Record
High Jump (Men) Long Jump (Men) High Jump (Women) Long jump (Women)	Javier S. (2m 45 cm) Mike P. (8m 95 cm) Stefka K. (2m 9 cm) Galina C. (7m 52 cm)	Chandra Pal (2m 17 cm) Amrit Pal (8m 8 cm) Bobby A. (1m 91 cm) Anju G. (6m 83 cm)

Find out from the table —
Look at the Women's World Records. What is the difference between the longest jump and the highest jump?

Answer 1

We know
1 m = 100 cm
Long jump of Galina C. = 7 m 52 cm
= (7$\times$100) cm + 52 cm
= 700 cm + 52 cm
= 752 cm
High jump of Stefka K. = 2 m 9 cm
= (2$\times$100) cm + 9 cm
= 200 cm + 9 cm
= 209 cm
Now, to find the difference between the longest jump and the highest jump, we have to subtract 209 cm from 752 cm.

$\begin{array}{ccccc}& 7& 5& 2& \mathrm{cm}\\ -& 2& 0& 9& \mathrm{cm}\\ & 5& 4& 3& \mathrm{cm}\\ & & & & \end{array}$

∴ Difference between the longest jump and the highest jump = 543 cm
= 500 cm + 43 cm
= (500$÷$100) m + 43 cm
= 5 m + 43 cm
= 5 m 43 cm
