A yellow taxi cab went from Downtown to the Beachside and back at an average speed of 2/3 miles per hour. If the distance from Beachside to Downtown is 1 mile, and the trip back took half as much time as the trip there, what was the average speed of the yellow taxi cab on the way to Beachside?
A1/3
B1/2
C3/4
D2/3
E3/2
Hi....
Let the time taken be x while going and therefore\(\frac{x}{2}\) on return trip.
So total time =x+x/2=3x/2..
Distance=1+1=2..
So average speed=2/(3x/2)=4/3x..
So 4/3x=2/3....x=2
Now
