Question

black panther ran 567.6km to the east 2.3 hours then turned around and ran 221.8km to the west in 1.2 hours. what was his average velocity during the trip in km/h?

Answer 1

98.8 km/h

Explanation:

Given that:

Distance traveled towards east,
`D_1` = 567.6 km

Time taken towards east,
`t_1` = 2.3 hours

After turning back:

Distance traveled towards west,
`D_2` = 221.8 km

Time taken towards west,
`t_2` = 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:
`\text{Average Velocity= }\frac{\text{Displacement}}{\text{Total Time Taken}}`

Here, Displacement will be GI - IH =
`D_1-D_2` =567.6 - 221.8 = 345.8 km

Total time taken = t_1+t_2 = 2.3 + 1.2 = 3.5 hours

`\text{Average Velocity= }(345.8)/(3.5) = \bold{98.8\ km/h }`

The answer is:

Average Velocity = 98.8 km/h
