Integers L-1 | Chapter 1 | Operations on Integers | Class 7 | Arsh Ma'am 

To calculate the time it takes for the elevator to reach -400m, we first need to find the total distance it travels. Initial position: 30m above ground level Final position: -400m below ground level Total distance = 30m + 400m = 430m Now, we divide the total distance by the rate of descent to find the time: Time = Total distance / Rate of descent Time = 430m / 5m/min Time = 86 minutes So, it will take 86 minutes for the elevator to reach -400m.

Started at - 30m To reach - 400 :. Total distance - 400+30=430m :. Rate of descending= 430÷5=86 m/min

HOMEWORK- Speed = 5m/min Current level= 30 m above ground Level to be reached= 400 m below ground Distance between both of them= 430 units or (-430) Now, 430 ÷ 5 = 86 = 86 mins Hence, it will take 86 minutes to reach 400 meters below ground with the given speed

Mam you are the best teacher

To calculate the time it takes for the elevator to reach -400m, we can use the formula: Time = distance/speed Given that the elevator descends at a rate of 5 m/min and needs to reach a depth of 400 m (30 m above ground level to -400 m), we can plug these values into the formula: Time = 400m/5m/min Time = 80 min So, it will take 80 minutes for the elevator to reach -400m.

Avinash Ans = 86 minutes

Speed=5m/min Total distance covered by it =30+400=430m Time =speed/distance 430/5 Ans= 86 min

86 is the answer of hw

Speed= 5m/min Total distance coverd by it= 30 + 400 = 430m Time = speed/time = 430/5 =86 minute

Yes

MAM, You are late in explaining syllabus ❤ Mam it's may , but till now we haven't done that much chapters that we could do Ma'am I am not your Hater, I am a big student of you, I am just requesting you.

mam the answer is 86 min bcz we 1st find the total distance which is 30m+400m which gives us 430 and then we do the formula time= distances by rate so for us its going to be time= 430 by 5m/min and we get the answer as 86 min so there for it takes 86 min's to reach -400m. :D

Mam please start class 6 classes of maths

❤❤Good evening ma'am 😊 Myself Anshika 😊☺️ The Answer of the homework question are as follows:- 1st step -- We have to add 30m - ( -400 )m = 30 + 400 = 430m 2nd step -- We use the formula [ Time = Distance / Speed ] 3rd step -- We use this formula as Time = 430 / 5 Time = 86 Therefore, the time taken by elevator is 86 m per minutes or 1 hours 26 minutes.😊😊😅

HELLO,MAM, HOMEWORK:- it will take 86 minutes for the elevator to descend to -400 meters.

Mam when live class you will take mam

Home work My name is Aadrsh Answer is 86

Man please give the link of 2 session

speed=5m/min total distance= 30+400=430 time = 430/5 = 86 mins
