Choose the correct choice from the following choices.
A) 1000 meters B) 1050 meters C) 1200 meters D) 1250 meters E) 2500 meters
Explanation:   We need to get the answer in meters. So we will first of change distance from km/hour to meter/sec by multiplying it with 5/18 and also change 15 minutes to seconds by multiplying it with 60.   Speed=10âˆ—5/18=25/9m/sec   Time=15âˆ—60seconds=900seconds   Distance=Timeâˆ—Speed/Distance=25/9âˆ—900=2500meter   Option 2500 meters
<result>E</result>
