If S = (4t + 3)(t – 2), find ds/dt when t = 5 secs.

If S = (4t + 3)(t – 2), find ds/dt when t = 5 secs.
A. 50 units per sec
B. 35 units per sec
C. 22 units per sec
D. 13 units per sec

Correct Option: Answer is B

Solution:
s=(4t+3)(t−2)
ds/dt=(4t+3)(1)+(t−2)(4)
= 4t+3+4t−8
= 8t – 5
ds/dt (t=5secs)=8(5)−5
= 40 – 5
= 35 units per sec
