Question

If the distance covered by an object in time t is given by s t , where s t is in meters and t is in seconds, what is the distance covered in the interval between 1 second and 4 seconds?

a 72 meters
b 75 meters
c 78 meters
d 80 meters
e 81 meters

Answer 1

The distance covered in the interval between 1 second and 4 seconds is 15 meters.

Step-by-step explanation:

The distance covered by an object in time t is given by the equation s = t t, where s is in meters and t is in seconds.

To find the distance covered in the interval between 1 second and 4 seconds, we need to subtract the distance at t=1 second from the distance at t=4 seconds.

s4 = 42 = 16 meters

s1 = 12 = 1 meter

The distance covered in the interval between 1 second and 4 seconds is s4 - s1 = 16 - 1 = 15 meters.
