do you know what the word average means ?? and how to calculate that??
basics of 7th class mathematics my dear watson basic ! 
in 48 hours i travelled @ 45Km/hr before a 10 km stop for fuel fill then @ 65 km/ hour for 51 km then stopped for tyre pressurre check and 32 km @ 75km /hr when i got 2 tyres flat. waited for 3 hours to get both wheels fixed then travelled 90 Km @ 110 km/hr before reaching destination. what was my average speed at destination 183Km away from start.
