The answer is B - Current Y has a greater potential difference, and the charges flow at a slower rate.
I just took the quiz
- Speed is the rate of change of distance with time while velocity is the rate of change of displacement with time.
- Speed is a scalar quantity while velocity is a vector quantity.
- Speed cannot be negative but velocity can be negative.
Hope you could get an idea from here.
Doubt clarification - use comment section.

Answer:
v = 98.75 km/h
Explanation:
Given,
The distance driver travels towards the east, d₁ = 135 km
The time period of the travel, t₁ = 1.5 h
The halting time, tₓ = 46 minutes
The distance driver travels towards the east, d₂ = 215 km
The time period of the travel, t₁ = 2 h
The average speed of the vehicle before stopping
v₁ = d₁/t₁
= 135/1.5
= 90 km/h
The average speed of vehicle after stopping
v₂ = d₂/t₂
= 215/2
= 107.5 km/h
The total average velocity of the driver
v = (v₁ +v₂) /2
= (90 + 107.5)/2
= 98.75 km/h
Hence, the average velocity of the driver, v = 98.75 km/h
What is your question exactly? I'm confused?
