If a root initially 5 cm long grows at a constant rate of 2 cm per day, what will be its length after 3 days, assuming arithmetic growth?
A
11 cm
B
10 cm
C
9 cm
D
8 cm
Correct Answer
Option A
Detailed Explanation
In arithmetic growth, the length at time 't' is given by L_t = L_0 + rt. Here, L_0 is 5 cm, r is 2 cm/day, and t is 3 days. Thus, L_t = 5 + (2 * 3) = 11 cm.
