Answer:
98.8 km/h
Step-by-step explanation:
Given that:
Distance traveled towards east, [tex]D_1[/tex] = 567.6 km
Time taken towards east, [tex]t_1[/tex] = 2.3 hours
After turning back:
Distance traveled towards west, [tex]D_2[/tex] = 221.8 km
Time taken towards west, [tex]t_2[/tex] = 1.2 hours
To find:
Average Velocity during the trip in km/h = ?
Solution:
First of all, let us consider the image attached in the answer area:
Let the black panther runs to point I from G and the turns back to point H.
GI = 567.6 km
IH = 221.8 km
Formula for Average Velocity is given as:[tex]\text{Average Velocity= }\dfrac{\text{Displacement}}{\text{Total Time Taken}}[/tex]
Here, Displacement will be GI - IH = [tex]D_1-D_2[/tex] =567.6 - 221.8 = 345.8 km
Total time taken = t_1+t_2 = 2.3 + 1.2 = 3.5 hours
[tex]\text{Average Velocity= }\dfrac{345.8}{3.5} = \bold{98.8\ km/h }[/tex]
The answer is:
Average Velocity = 98.8 km/h
