Solution:
i. Consider a travel from A to B
= 0, = 16 −2 , = 10
= +
= 0 + (16)(10)
= −1
Consider a trip from B to C:
= 160 −1 , = 8 −2 , = 15
= +
= 160 + (8)(15)
= −1
-1
Maximum speed car is 280 ms which is present in the station C
ii. Consider a trip from C to D station:
= 280 −1 , = 0, = 15
= +
0 = 280 + (15)
280
= −
15
= − . −2
