Answer:

The answer is option D

Step-by-step explanation:

From the question we are finding the final velocity of the bicycle

To find the final velocity given the initial velocity , acceleration and time we use the formula

v = u + at

where

v is the final velocity

u is the initial velocity

a is the acceleration

t is the time

From the question

u = 10 m/s

a = 6 m/s²

t = 20 s

Substitute the values into the above formula and solve

That's

v = 10 + 6(20)

= 10 + 120

We have the final answer as

130 m/s

Hope this helps you.
