1.	The odometer of a car reads ` 2000 km ` at the start of a trip and `2400 km` at the end of the trip . If the trip took `8 h` , calculate the average speed of the car in `km//h and m//s`.
Answer» Correct Answer - `50 km//h` ; `13.9 m//s` Distance travelled , `s =` final reading - initial reading `= 2400 - 2000 = 400 km` time taken , `t = 8 h` Average speed `= (s)/(t) = (400)/( 8) = 50 km//h = ( 50 xx 1000 m)/(60 xx 60 s) = 13.9 m//s`
