The train's average speed during that 24.8 seconds is 

                      (1/2) (4.82 m/s + 7.09 m/s)

                =    (1/2)    (11.91 m/s)

                =           5.955 m/s .

Traveling at an average speed of  5.955 m/s  for  24.8 sec,
it covers

                 (5.955 m/s) x (24.8 sec)  =  147.68 meters  .

romanna [79]
To get the solution you must need to draw a force triangle. Attach the head of the 60N north force arrow with the tail of the 60N east force arrow. The subsequent is the arrow connecting he tail and head of the two arrows. 
You get a right angled triangle, and the resultant is (60^2 + 60^2) ^0.5 = 84.85 N or 85 N northeast.

Nonamiya [84]
N2 = 3*n1
T2 = 2*T1
V1 = V2

(n2 * T2)/P2 = (n1 * T1)/P1
3 n1 * 2 T1 / P2 = n1 *T1 / P1
P2 = 6*P1

Since P2 is 6P1, it is 6 times greater than original pressure
