b) 1 kg pure milk contains 0.250 kg of fat. How much milk

Answer 1

Step-by-step explanation:

Now it is given that the car covers a distance (d) = 240 km with some speed. Now it is given that the speed is increased by 20 km/hr. it will cover the same distance in 2 hours less. Therefore new speed = (V + 20) km/hr

b. In 1 kg of milk, fats is =0.245 kg
