Example 8.2 The odometer of a car reads2000 km at the start of a trip

1.	Example 8.2 The odometer of a car reads2000 km at the start of a trip and2400 km at the end of the trip. If thetrip took 8 h, calculate the averagespeed of the car in km hl and m s.
Answer» ANSWER: GIVEN : Initial odometer reading=2000km Final odometer reading=2400km Total distance= Final distance- Initial distance =2400-200=400km Total time=8h AVERAGE SPEED =? Formula to be USED : Average speed= Total Distance/Total time Average speed in Km/hr: Average speed=400/8 =50 km/hr Average Speed in m/s: 1km/hr=5/18 m/s ∴50km/hr=50x5/18=250/18=13.88m/s Read more on Brainly.in - brainly.in/question/739878#readmore Explanation:

Answer»

Initial odometer reading=2000km

Final odometer reading=2400km

Total distance= Final distance- Initial distance

=2400-200=400km

Total time=8h

Formula to be USED :

Average speed= Total Distance/Total time

Average speed in Km/hr:

Average speed=400/8

=50 km/hr

Average Speed in m/s:

1km/hr=5/18 m/s

∴50km/hr=50x5/18=250/18=13.88m/s
