Solution

first je t^{'} s speed : 787

second je t^{'} s speed : 703

Solution steps

Translate the problem into an equation:

x \cdot 9 + (x - 84) \cdot 9 = 13410

Solve for

x, x \cdot 9 + (x - 84) \cdot 9 = 13410 : x = 787

Find speed

first je t^{'} s speed : 787

second je t^{'} s speed : 703
