For some reason I can’t send a picture but I think it is:
First column is E = mgh
Second column is W=Fd (I think)
Where distance is calculated as 100*10 (to find the distance he travelled down the road)
Rearranging it to F = W/d, which is 100,000/1000
Making the answer D

for the distance down the road, why do we need to multiply it by 10? could you explain thanks!
See this is where i’m not 100% confident on it to be honest but because its a resistive force, we want to work out the distance travelled along the slope - we are given the loss in vertical height as 100m and the conversion as 1m loss in vertical per 10m travelled across the road
