Given that bike consumes 20 ml of petrol.
Given that the speed is in the range of 25 - 50 km/hr, then it consumes 40 km of petrol.
Now,
According to the question:
(1)
Given that bike is driven at speed of 40 km/hr for first 10 km.
It is not in the range of 25 - 50 km/hr, So, it consume 20 ml of petrol.
= > 10 * 20 = 200 ml.
(2) Given that bike is driven at a speed of 60 km/hr for next 30km.
Here, it is in the range of 25 - 50 km/hr, So it consume 40 ml of petrol.
= > 40 * 30 = 1200 ml.
(3) Given that bike is driven at a speed of 30 km/hr for the last 10 seconds.
It is not in the range of 25 - 50 km/hr, then it consume 20 ml of petrol.
= > 10 * 20 = 200 ml.
Hence,
Total petrol consumed = 200 + 1200 + 200 ml
= > 1600 ml
= > 1600 * (0.001) litres
= > 1.6 litres.
Therefore in traveling at a distance of 50 km, it will consume 1.6 litres.
Hope this helps!
