Question

A parachutist dived from a height of 514m into a valley 62 m deep. Find the time
taken by him to reach the land, if he is falling at a speed of 18m/min.

Answer 1

Answer:

Also speed of the parachutist will be 18 mtrs / minute. Time taken to cover the distance will be 576 / 18 = 32 minutes.

Answer 2

⇝GIVEN :

• Height = 514 m
• Depth = 62 m
• Speed = 18m/min

• Time = ?

⇝SOLUTION :

❒Formula for Time :

${\red{\bigstar \: \: {\orange{\underbrace{\underline{\overbrace{\overline{\mathfrak{Time = \frac{distance}{speed} }}}}}}}}}$

❒Now,

${\mapsto{\bf{Time = \frac{distance}{speed} }}}$

${\leadsto{\sf{Time = \frac{514 + 62}{18} }}}$

${\leadsto{\sf{Time = {\cancel\frac{576}{18} }}}}$

${\large{\purple{:{\mapsto{\underline{\boxed{\bf{32 \: min}}}}}}}}$

❒So,

${\red{\underline{\boxed{\green{\mathfrak{Time = 32 \: min}}}}}}$
