Question

an elevator is 25m below the ground level and it ascend at the rate of 5 m/min . find the time taken by it to reach 50 m above the ground​

Answer 1

Answer:

10 min

Step-by-step explanation:

${\small{\tt{Distance \: travelled \: \: by \: \: elevator = 25m}}}$

${\small{\tt{Speed \ \: of\ elevator = 5m/min}}}$

${\small{\tt{Time \: taken \: = \frac{distance}{speed}}}}\\{\small{\tt{=\frac{25m × min}{5m}}}}\\{\small{\tt{=5 \: min}}}$

${\small{\tt{Time \: taken \: to \: cover \: 1m \: distance = \frac{5}{25}min = \frac{1}{5}min}}}$

${\small{\tt{Time \: taken \: by \: it \: to \: reach \: 50 m \: above = \frac{1}{5} × 50 = 10min}}}$
