Question

A toy jeep is 12 1/2 inches long, while an actual jeep measures 18 3/4 feet long. What is the value of the ratio of the length of the toy jeep to the length of the actual jeep? What does the ratio mean in this situation?​

Answer 1

A thief is running away in a car with velocity of `20 m//s`. A police jeep is following him, which is sighted by thief in his rear view mirror, which is a convex mirror of focal length 10 m. He observes that the image of jeep is moving towards him with a velocity of `1 cm//s`. if the magnification of mirror for the jeep at that time is `1/10`. Find <br> (a) the actual speed of jeep, <br> (b) rate at which magnification is changing. <br> Assume the police's jeep is on the axis of the mirror.

Answer 2

Answer:

ratio: 104:1875

Step-by-step explanation:

toy jeep = 12.5 inches

12.5 inches = 1.04 feet

real jeep = 18.75 feet

1.04 / 18.75 = 0.055 104:1875
