Jack and Blake are jogging side-by-side along the Main level trail at a speed of 0.75 m/s. 



Jack sees the end of the trail 35 m ahead and decides to speed up to reach the end sooner than Blake. At the instant Jack is 35 m from the end, Jack accelerates at a constant rate of 0.5 m/s2 while Blake continues at the original constant speed. 



a. How long does it take Jack to reach the end of the trail (from 35 m away)? 



b. Once Jack reaches the end of the trail, he immediately turns around and heads back with a constant speed of 0.85 m/s. How long does it take him to meet up with Blake? 



c. How far are they from the end of the trail when they meet?
