Question

(a) Calculate the speed of the car in km/min during the time

• A. $0.75km/min$
• B. $0.80km/min$
• C. $0.90km/min$
• D. $1km/min$

Answer 1

The correct option is A $0.75km/min$

Given data

Initial reading of the odometer of the car $=57321.0km$

Final reading of the odometer of the car $=57336.0km$

We know that

Distance covered by the car = Final reading of the odometer of the car - Initial reading of the odometer of the car

$=57336.0-57321.0=15km$

The given car starts at $8:30a.m.$ and stops at $8:50a.m$.

Therefore, time taken by the car to cover the distance is $(8:50—8:30)$ min $=20min$

Distance covered by the car $=15km$

Time taken by the car =$20min$

$speed=\frac{Distancecovered}{Timetaken}$

$=\frac{15}{2}=0.75km/min$
