Answer 1

Answer:

to find its actual distance you should use a formula

Explanation:

speed is equals to distance upon time here speed is given and time is 1 hr so can easily find you answer..

thank you I hope this will help you....if yes then give me alike

Answer 2

Given,

If novak djokovic walks at 15km/hr instead of 11km/h, he would have walked 20km more.

To find,

Actual distance travelled by him.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Let,

He travelled for = x hours

(Time will be same in both cases. Without same time of journey, we cannot compare the total travelled distances with two different speeds.)

So, in 15 km/h speed :

Travelled distance = (15 × x) = 15x km

In 12 km/h speed :

Travelled distance = (11 × x) = 11x km

According to the data mentioned in the question,

15x - 11x = 20

4x = 20

x = 5

Travelling time = 5 hours

Actual speed = 11 km/h

Actual travelled distance = (11×5) = 55 km

Hence, he actually travelled a distance of 55km
