Question

There are 20 windmills with a constant distance between each pole. A car takes 22 seconds to reach the 12th pole. How much time will it take to reach the last pole?

Answer 1

Answer:

Step-by-step explanation:

To reach 12th pole, the car took 22 seconds. Since you didn't mention the car’s start point, let's assume the following scenarios:

Scenario 1

If the pole 1 is the start point of car then,car is

At 0 zero seconds = in pole 1

At 22th seconds = in pole 12

So it has covered distance of 11 poles in 22 seconds.

So, time taken to cover distance between 2 poles is 2 seconds (22/11)

And hence the car would reach 20th pole in 38 seconds (2*19)

Scenario 2

If the car starts at a distance from 1st pole equal to distance between two poles, then car is

Let's assume distance between the 2 poles as x

At zero seconds = x distance away from 1st pole

At 22 seconds = in 12th pole

So it has covered distance of 12 poles in 22 seconds.

So, time taken to cover distance between 2 poles is 1.83 seconds (22/12)

And hence the car would reach 20th pole in 36.6 seconds (1.83*20)
