Aperson travelled in the -x direction at a constant speed of 2.5 m/s. the person's final position is -10.0 m, and the initial position of the person is 10.0 m. determine the amount of time required for the person to travel. a) 4.0 s
b) 6.0 s
c) 8.0 s
d) 12.0 s

(c) time required to travel = 8 sec

Explanation:

We have given the final position = -10 m on x axis

And the initial position =10 m

So total distance = 10-(-10)=20 m

The speed is given as 2.5 m/sec

We have tof ind the time required by the person to travel

Time is given by

So the option (c) is correct option
