Answer 1

T he speed, at which its image appears to approach the driver, will be​ 25 m/s.

Explanation:

We are given that:

• Rera view of car = Plane mirror
• Reversing speed of the car =5 m/s
• To find the speed at which its image appears to be approaching the driver =?

Solution:

Speed of object in the mirror = 5 v

Here "v" is the original speed.

Now put the values;

Speed of object = 5 (5) = 25 m/s

Thus the speed, at which its image appears to approach the driver, will be​ 25 m/s.
