Question

Nilesh wants to make sure he can throw the javelin in the minimum required distance so he can advance in the competition. If his current best throw is $60$ yards, and one yard is approximately $0.9144$ meters, how much further, to the nearest yard, must he throw in order to achieve the minimum required distance of $68.58$ meters to qualify for the Olympics? (Judgement is done on the basis of 'metres').

• A. 15
• B. 19
• C. 23
• D. 31

Answer 1

The correct option is A 15

Given Nilesh throw jawline $60$ yard and one yard $=0.9144$ miters

Then Nilesh throw jawline $=$ $60\times 0.9144=54.864$ meters

But the required distance of $68.58$ meters $=$ $\frac{68.58}{0.9144}=75$ yard

Then nilesh throw jawline extra $=75-60=15$ yard.
