A ferry traveling along the river at a constant rate covers of the distance between two ports in of
an hour. At this rate, what fraction of the distance between the two ports can the ferry travel in one
hour?
(A) 3/24 (B) 1/3 (C) 7/18 (D) 25/42


Sagot :

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.
