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
Then in 12.8 kg of milk, fats will be
=0.245×12.8 kg
=3.1360 kg
