the odometer of a car treats 57321.0 km when the clock shows the time 8:30 a.m. what is the distance moved by the car if at 8:50 a.m. the odometre reach has changed to 57336.0 km calculate the speed of the car during this time. express the speed in km/h
Answers
Answer:
The Distance Covered
=57336-57321
=15 km
Speed of the car
= 15 km in 20 mins
=3×15 km in 3×20 mins
=45km in 60mins
=45km/h
Explanation:
The car moves 15 km from 8.30am to 8.50am.
We get the stat that it moved 15 km in 20 mins.
So in 1 minute it moves 15/20 km,
in 60mins (1h) it moves (15/20) ×60
=45 Km
Answer:
Solution:
The initial reading of the odometer of the car =57321.0 km
The final reading of the odometer of the car = 57336.0 km
The car starts at 8:30 AM and stops at 8:50 AM.
Distance covered by car = (57336 - 57321) km = 15 km
Time taken between 08:30 AM to 08:50 AM = 20 minutes = 20/60 hour = 1/3 hour
So Speed in km/min
Speed = (Distance travelled)/ (Time)
= (15km)/ (20min)
= 0.75km/min
Speed in km/h Speed = (Distance travelled)/ (Time)
= (15km)/ (1/3h)
= (15 x 3) km/ (1h)
= 45km/h
