The odometer of a car reads 24830 km at 1:25pm, 24865 km at 2:05 pm and 25005 km at3:15 pm respectively. Calculate the speed of thecar in km/h from 1:25 pm to 3:15 pm and thenexpress the speed in m/s.(Ans: 95.5 km/h, 26.53 m/s)(c)
Answers
Answer:
Explanation:
First calculate the total distance traveled using the odometer.
starting reading at 1:25 was 24830 km
end reading at 3:15 was 25005
Therefore total distance traveled was 25005km - 24830km = 175 km
Total time taken between 1:25pm and 3:15 pm 3:15
-1:25
1hr 50 mins
1 and 5/6 hours = 11/6 hrs
Speed = distance/time
175 ÷ 11/6 = 175 × 6/11
95.45 km/hr
speed in m/s.....multipy by 1000/3600
95.45 × 10/36
= 26.52 meters/second

26.52 m/s
Explanation:
First calculate the total distance traveled using the odometer.
starting reading at 1:25 was 24830 km
end reading at 3:15 was 25005
Therefore total distance traveled was 25005km - 24830km = 175 km
Total time taken between 1:25pm and 3:15 pm 3:15
-1:25
1hr 50 minutes
1 and 5/6 hours = 11/6 h
Speed = distance/time
175 ÷ 11/6 = 175 × 6/11
95.45 km/h
speed in m/s=>multiply by 1000/3600
95.45 × 10/36
= 26.52 m/s
