Dirgh starts its vehicle for trick and his audometer his 1500 km at the start and 2100 km at the end of the trip .If took 12 hours for the trip then calculate the everage trip km /h and m/s
Answers
Answer:
50,13.888
Explanation:
distance travelled = final odometer reading - initial odometer reading
distance = 2100 - 1500
distance = 600 km
time taken to travel = 12 hours
average speed = total distance / total time
avg speed = 600/12 = 50kmph
1 kmph = 5/18 m/s
50kmph = 5/18 x 50m/s
= 13.88m/s

Given that, an odometer of a vehicle reads 1500 km at the start of a trip and 2100 km at end the end of trip.
Means, initial distance = 1500 km and Final distance = 2100 km
Also given that, the trip takes 12 hours. So, total time taken to cover the trip is 12 hours.
We have to find the average speed of the trip in km/hr and m/s.
Now,
(a) Total distance covered by vehicle = Final distance - Initial distance
= (2100 - 1500) km= 600 kmTime
= 12 hours
So,
Average speed = (Total distance covered)/(Total time taken)
= 600/12
= 50 km/hr
Therefore, the average speed of the vehicle in km/hr is 50 km/hr.
(b) In second part, we have to find the average speed of the vehicle in m/s.
From above calculations we have average speed = 50 km/hr. To convert km/hr into m/s, multiply with 5/18.
So,
Average speed = 50 × 5/18= 13.89 m/s
Therefore, average speed of the vehicle in m/s is 13.89 m/s.
