Answer:
Rajesh speed > 2.5 km
Step-by-step explanation:
Two friends Rajat and Rajesh are 12.5 km apart. If they travel in opposite directions, they meet after 2.5 hours. If Rajesh travels faster, what is his speed?
As they travel in opposite directions
it means they are approaching each other so resultant speed is addition of their speed
Distance = 12.5 km
Time = 2.5 hr
Speed = Distance/Time
Resultant Speed = 12.5/2.5 = 5 km/hr
Rajesh + Rajat speed = 5 km /hr
Rajesh Travels faster
so
Rajesh speed > 2.5 km
