Question

2. A tanker contains 452 litres of milk. Due to leakage in the tanker,the quantity of milk in it decreases at the rate of 12 litres per hour.How much milk will be left in the tanker after 11 hours?

Step by step explanation.​

Answer 1

Answer:

1) Given :

Altitude descended by Monica in 1 min = 100 m

Time for which she descended = 3 mins

Starting altitude of Monica = 728 m

To Find :

Altitude Monica lose in 3 minutes and her final altitude = ?

Solution :

The altitude Monica descended in 3 minutes at a rate of 100 m per minute is :

= m

= 300 m

So final altitude of Monica is :

= (728 - 300 ) m

= 428 m

Hence , Monica lose 300 altitude in 3 mins and her final altitude is 428 m

2)TOTAL QUANTITY OF MILK=452L

DUE TO LEKAGE THE QUANTITY OF MILK DECREASE=(12*5)

=60

MULK LEFTVIN TANKER=(452-60)

=392L
