Draw a small matrix.
A P M
Rate
Time
Dist.
Start with easy stmt. Stmt 2.
Not info about A amd P. Hence insueff.
Stmt1
Let P drove for time "t" , therefore A drove for "t+1"
Let x be the speed for P, there fore speed pf A = x -5
fill the matrix
A P M
Rate x-5 x
Time t + 1 t
Dist.
no more info given. hence insueff.
Combine the 2 stmst together
A P M
Rate x-5 x 50
Time t + 1 t 9
Dist. 450
(x-5) (t+1) + xt + 450 = 1500
here we have 2 variables and 1 eqn.. not possible to find values for x.
hence choice E
