Starting from rest, a boat increases its speed to 4.92 m/s with constant acceleration.
(a) What is the boat's average speed?
(b) If it takes the boat 5.07 s to reach this speed, how far has it traveled?

physics 
charrice,
initial velocity = 0 m/s
final velocity = 4.92 m/s
constant acceleration so,
(a) average velocity =
(initial velocity + final velocity)/2
(b) distance = average velocity x time
substitute and calculate
