The odometer of a car reads 57321.0 Km when the clock shows the time as 8.30 a.m. The odometer reading changes to 57336.0 Km at time 8.50 a.m. The distance, moved by the car in these 20 minutes,equal------

• A. $15Km$
• B. $21Km$
• C. $26Km$
• D. $36Km$

Answer 1

The correct option is A $15Km$

Initial odometer reading, $A_1=57321km$

Final odometer reading, $A_2=57336km$

Difference in reading, $A_2-A_1=57336-57321=15km$

Hence, distance travel is $15km$
