KiRa [710]

Answer:

The car travel 2.52 m

Explanation:

This problem gives us the time and speed of the car with the echolocation system, and they ask us for the distance traveled, we can use the report motion equation.

Let's start by calculating the relative speed of the two cars, which in this case is the initial mass because the second vehicle is at rest.

    v = d / t

    d = v t

    d = 14  0.18

    d = 2.52 m

The car travel 2.52m

A swarm of bees has an average velocity of 0.20 meters per second. How far will they travel in 2 minutes? Show equation, substit
kenny6666 [7]

Answer:

24 metre

Explanation:

From the available information in this question,

The swarm of bees moves at 0.20 per second

If it moves at

O.20 = 1 second,

We have a minute to be = 60 seconds

So in one 1 minute the velocity =

0.20 x 60 seconds

= 12 meters

The 2 minutes = 60 seconds x 2

2 minutes = 120 seconds

120 x 0.20 = 24 meters

So in 2 minutes these swarm of bees are going to travel a distance of 24 metres
