⟩ A person was fined for exceeding the speed limit by 10mph. Another person was also fined for exceeding the same speed limit by twice the same. If the second person was traveling at a speed of 35 mph, find the speed limit?
Threshold speed = x mph
let us assume that the 1st person was travelling at (x+10)mph
so it's obvious that the 2nd person travels at 2*(x+10)mph = 35mph; which means x = 7.5 which is the threshold or the speed limit.
So according to me the ans is 7.5mph.
