Question

The odometer of a vehicle has an initial reading of $22256\text{km}$. After the trip, it shows a reading of $22356\text{km}$. If the time taken for the trip is $5$ hours, what is the average speed of the vehicle?

• A. $20\text{kmph}$
• B. $30\text{kmph}$
• C. $40\text{kmph}$
• D. $50\text{kmph}$

Answer 1

The correct option is A $20\text{kmph}$

Given:
Odometer reading, before the trip $=22256\text{km}$
Odometer reading, after the trip $=22356\text{km}$
So the distance travelled in the trip$=22356-22256=100\text{km}$
Time taken for the trip $=5\text{hr}$

Average speed = $\frac{\text{Total distance travelled}}{\text{Total time taken}}$

$\therefore$ Average speed $=\frac{100}{5}=20\text{kmph}$
