i have never done one of these ever so tell me if my advice is ****, but can you mark a distance 'X' from A to vertically below B and then do some trig identity/differentiation work? I got a value of x between 0 and 2km and a time which seems quite short so idk

Well it's a 10 marker and what value did you get for x and the time?Literally none of my friends could do this question lol

it wasnt an exact length/time and i have a weird feeling it should be, i got the length from A to the point vertically under B to be 0.7937254... and time in hours to be 0.44196..

you must remember to come back and tell me the answer, im really curious now
8. i mean without knowing the horizontal distance from d to b its not possible
