Answers
Explanation:
Smoking is banned in petrol stations because petrol is a flammable substance which also has low ignition temperature . The Sparks from the cigarette can move towards petrol which can cause a huge fire which can not b easily doused.
Total distance travelled -
speed = distance x time
distance = speed / time
40/2 km/h = 20 km
light years are used to measure distance between stars and Earth.
A light year is unit if distance not time .
Think of it as bigger , badder cousin of the inch, the mile , km and furlong .
Obesity is caused due to overeating .

it can be prevented by taking proper exercise
eating limited food
