Answer:At 7:30 am, the odometer reading of the car =28568 km
Speed of the car =4 km min
−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 × time interval
=4×105 km=420 km
Hence the odometer reading at 9:15 am
=28568+420=28988 km.
