What i dknt think u were meant to put a specific difference u were meant to explain if it was faster or quivker for diesel. And it wpuldnt have been 10 anyway because the charging time for the batteru was 40 minutes

I’m pretty sure the question was asking about whether electric or diesel would be quicker not specific speeds

It said they travelled at the same speed so I jus put how the electric car would have to stop to charge the car for 10 minutes to charge the battery enough to travel the last 100km

I got 0.016kg for the mass of the ice cube one (8.4) but I used simultaneous equations so I feel like there has to be an easier way

How do you do the mass one I didnt know what to do so I made an equation the equaled 5848J and got 0.09 but Ik it’s wrong

I said it was quicker for the disel car because the electric had to stop
