Hello Dear.

Here is the answer---

→→→→→→→→→→

Let the Distance covered by the man by foot be x km.

∴ Distance by Scooter = (14 - x)

For Foot.

Speed = 4 km/hr.

Distance = x km.

Using the Formula,

  Speed = Distance/Time

 Time(T₁) = x/4

For Scooter.

Distance = (14 - x)km.

Speed = 44 km/hr.

∴ Time(T₂) = (14 - x)/44

As per as the Question,

 T₁ + T₂ = 1

= 1

= 1

 10x + 14 = 44

  10x = 44 - 14

  10x = 30

    x = 3

∴ Distance covered by the man from the Foot = x

 = 3 hours.

∴ Distance covered by the man from Scooter = (14 - x) km.

 = 14 - 3

 = 11 km/hr
