alisha [4.7K]

Answer:

E. 44 meters

Step-by-step explanation:

The function that models the distance covered by the object is

s(t)=t^2+5t

where s(t) is in meters and t is in seconds.

The distance covered by the object after 1 second is

s(1)=1^2+5(1)=6m

The distance covered by the object after 1 second is

s(1)=5^2+5(5)=50m

The distance covered between 1 second and 5 seconds is

50-6=44m
