Answer:
Speed = 90 km per hour.
Step-by-step explanation:
Given : One of your friends lives 225 km away. It took him 2.5 hours to travel to the cottage.
To find : At what speed did he travel.
Solution : We have given that
Distance covered by friend = 225 km.
Time taken to travel = 2.5 hour.
Speed = [tex]\frac{Distance}{Time}[/tex].
Speed = [tex]\frac{225}{2.5}[/tex].
Speed = 90 km per hour.
Therefore, Speed = 90 km per hour.
