Taxi goes 261 km in 135 minutes.
We need speed in KM/HR
The distance is given in Km, but the time is NOT in hours. We convert minutes to hours as shown below:
Now, we can use Distance Formula to solve for the speed:
D = RT
Where
D is distance [given as 261 km]
R is speed [what we want to find]
T is time [2.25 hours]
Thus,
Average Speed = 116 kilometers per hour
