A) 28673 km
B) 28988 km
C) 29255 km
D) 28568 km
Correct Answer: B
Solution :
At 7:30 am, the odometer reading of the car = 28568 km Speed of the car \[=4\text{ }km\text{ }mi{{n}^{-1}}\] Total time interval between 7:30 am to 9:15 am = 1 hour, 45 minutes = (60 + 45) minutes = 105 minutes Required distance = speed of the car \[\times \] time interval \[=4\times 105\text{ }km=420\text{ }km\] Hence the odometer reading at 9:15 am \[=28568+420=28988\text{ }km\]You need to login to perform this action.
