The formula speed = distance ÷ time can be rearranged, just like any other equation. The formula can be rearranged in three ways: speed = distance ÷ time , distance = speed × time.
Speed tells us how slow or fast an object moves. Distance refers to extent of space between two events. Time refers to an interval separating two events.
ASSUME a ferry travels 1/7th of the distance between two ports in 3/5 hours , then it will be able to cover 5/6th part of the distance between two ports in 3.5 hours.
Distance that the ferry would be able to trave in 1 hour can be found out by :
unit rate=distance / time
=1/7÷3/5
Reciprocal:
=1/7×5/3
=5/21th of distance per hour
The distance that the ferry would be able to travel in 3.5 hours:
= (5/21 ) ×3.5
=(5/21)×(7/2)
Further solving:
=(5/3)×(1/2)
5/6th of the distance between two ports.
