Anyone good at algebra?

Hi all,

This might seem weird but here goes. I drove my 3P a total 1168 miles on a combination of stock 20”/235 wheel/tire combo and 18”/255 wheel/tire combo and got 249wh/mi.

I swapped to 18”/255 wheel/tire and drove 625.4 miles and got 239wh/mi. I need to know what the wh/mi was when I drove 542.6 miles on the stock 20”/235 combo. Is there a way to figure the wh/mi for the 542.6 miles when I drove on the 20” wheels and 235 tires?

I don't think so unless you set a trip meter as you changed the wheels.

Misunderstood at first. Here is the calculation. 261 on the 20".

Miles Wh/Mi Total (Watts)
Total 1168 249 290832
18” 625 239 149375
20” 543 261 141457

Thanks. Can you tell me the formula you used to find out the wh/mi on the 20 inch wheels?

 

[cypho]

Total Miles = 1168
18" miles = 625.4

1168-625.4 = 542.6 miles on 20's

Total kWH = 291
18" kWH = 150

291 - 150 = 141 kWh on 20's

141 kWh / 542.6 miles = 0.25985993365 kWh / Mile = 259.85993365 Wh/mi

Is that algebra? It feels more like subtraction.

you got me, I should have said math. Thank you for the help.
