Answer :
∴ Both X and Y covers 27 km in opposite directions after 3 hours.
----------------------------------------------------------------------
Step-by-step explanation :
Given :
⇢ Speed of X is 5 km per hour
⇢ Speed of Y is 4 km per hour
⇢ Time for both X and Y is 3 hours.
----------------------------------------------------------------------
To Find :
⇢ Distance between X and Y after moving in opposite directions for 3 hours.
----------------------------------------------------------------------
According to question,
A) For X :
⇢ Speed = Distance/Time
⇢ 5 km/hr = Distance/3
⇢ Distance = 5 x 3
⇢ Distance = 15 km
B) For Y :
⇢ Speed = Distance/Time
⇢ 4 km/hr = Distance/3
⇢ Distance = 4 x 3
⇢Distance = 12 km
----------------------------------------------------------------------
⇒ As they move in opposite directions distance must be added,
⇢ 15 + 12
⇢ 27 km
----------------------------------------------------------------------
∴ Both X and Y covers 27 km in opposite directions after 3 hours.
