Answer:
Speed is 9.6 km/hr.
Explanation:
Speed is a scalar quantity with the determination of it as the ratio of distance to time. As the distance given is 50 km and the hour julie took is 5.2 hours. Distance is the measure of kilometers covered by her and time taken is the time required by her to cover that particular distance.
[tex]\text { speed }=\frac{\text {distance}}{\text {time}}[/tex]
[tex]\text { speed }=\frac{50}{5.2}=9.61 \mathrm{km} / \mathrm{hr}[/tex]
So the speed with which Julie rides is 9.6 km/hr. Since it is a scalar quantity, the direction is not taken into consideration.
