Answer 1

Answer:

Step-by-step explanation:

9. height of the submarine=3500

it ascends 1200m

new position=3500-1200=2300m below sea level

10. now balance of rehana in march=2000/-

in april she deposited means she added 700 to already existing balance=2000+700=2700/-

for the month of may she withdrew 1000 now her balance is=2700-1000=1700/-

12. he travelled towards east of delhi by 49m

and next travelled towards west of delhi by 80m

the distance from delhi is=80-49=31m

11. the whole distance an have 53m

the time taken for 1m =5s

now start with the first 5m it takes 25sec but it descends 1m again so it takes another 5 sec

time taken for first 5m=30s

so in the same way we can have 10*30=300s for 50m

we are left with 3 more metres=3*5=15sec

so total time=300+15=315 sec
