Answer 1

Answer:

2.85714268

Step-by-step explanation:

200/70=2.85714268

Answer 2

Given:

• Aeroplane is flying at the height of 1600m
• To land, it is descending its speed at the rate of 70m/minutes

To Find:

• How many time it will take to come to height of 200m

Solution:

In the question, it is given that an aeroplane is at the height of 1600 is descending downward at the rate of 70m/minutes and aeroplane is needed to come at the height of 200m.

Therefore,

• Aeroplane will cover total distance = 1600 - 200 = 1400m

We know that :

• $\large{\boxed{\small{\bf{Time~=~\dfrac{Distance}{speed}}}}}$

Hence,

Aeroplane will take time = $\small{\bf{\dfrac{distance}{speed}}}$

→ Aeroplane will take time = $\small{\bf{\dfrac{1400}{70}}}$

→ Aeroplane will take time = 20

Therefore,

• Aeroplane will take 20 minutes to come at the height of 200m.
