The speed of a car increases by 2 km/hr after every one hour. If the distance travelled in the first one hour was 35 km, what was the total distance travelled in 12 hours?
The distances travelled by the car in each hour will be 35,37,39,....
The distance travelled in the last hour will be 35+(12-1)2 = 35+12 = 57 km
Then, Total distance travelled in 12 hours = $$\dfrac{12}{2}(35+57) = 6\times92 = 552$$ km
