Question

I travel 25 km in 5.2 hours walking part of the way at 3 km per hour and covering a scooter the rest at 25 kilometre per hour how far away do I walk​

Answer 1

Answer:

The answer is 5Km.

Step-by-step explanation:

Let's suppose  x km is walked

Distance covered on Scotter = 25 - x km

We know that

Time = Distance/Speed

Time at walk = x/3  hour

Time at scotter = (25 - x)/24  hr

x/3  + (25 -x)/24  = 5/2    .....(1)

Now multiply by 24 on both sides of the equation (1).

=> 8x + 25 -x = 60

=> 7x = 35

=> x = 5

Thus the distance travelled by walking is 5 Km.

Answer 2

Answer:

let suppose x km to walk ‍♂️

let ridding on scooter 25–x
