Question

Dhanu has the longest jump of 3 metres 40 cm. Gurjeet is second. His jump is 20 cm less than Dhanu's. Gopi comes third. His jump is only 5 cm less than Gurjeet's jump.
• How long are Gurjeet's and Gopi's jumps?
___________________________________________
• Try and see how far you can jump.
• How far can you throw a ball? ____________ metres.
• Look for a big ball, like a football or volleyball. How far can you kick it? ___________

Answer 1

• We know
1 m = 100 cm
Length of Dhanu's jump = 3 m 40 cm
= (3$\times$100) cm + 40 cm
= 300 cm + 40 cm
= 340 cm
Since Gurjeet's jump is 20 cm less than that Dhanu's jump, we will subtract 20 cm from 340 cm to find the length of Gurjeet's jump.

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

Now,
Length of Gurjeet's jump = 320 cm
= 300 cm + 20 cm
= (300$÷$100) m + 20 cm
= 3 m + 20 cm
= 3 m 20 cm
Gurjeet's jump is 3 m 20 cm long.
Since Gopi's jump is 5 cm less than Gurjeet's jump, we will subtract 5 cm from 320 cm to find the length of Gopi's jump.

$\begin{array}{ccccc}& 3& 2& 0& \mathrm{cm}\\ -& 0& 0& 5& \mathrm{cm}\\ & 3& 1& 5& \mathrm{cm}\\ & & & & \end{array}$
Now,
Length of Gopi's jump = 315 cm
= 300 cm + 15 cm
= (300$÷$100) m + 15 cm
= 3 m + 15 cm
= 3 m 15 cm
Gopi's jump is 3 m 15 cm long.
