Question

A person is running west in Moscow at 2.1 km/hr relative to the ground and from his

perspective, another person is jogging east at 4.5 km/hr. What is the velocity of the jogger
relative to the ground?

Answer 1

4.96 km/hr

Step-by-step explanation:

Given that,

A person is running west in Moscow at 2.1 km/hr relative to the ground

Another person is jogging east at 4.5 km/hr.

We need to find the velocity of the jogger relative to the ground. Using the concept of relative speed, let V is the required velocity. So,

`V=√(2.1^2+4.5^2) \\\\=4.96\ km/hr`

So, the velocity of the jogger relative to the ground is 4.96 km/hr.
