A particle starts out from the origin. Its velocity, in miles per hour, is given by where t is the number of hours since the particle left the origin. How far does the particle travel during the second, third, and fourth hours (from t=1 to t=4)? Round to 3 decimals when necessary. Velocity (in miles per hour) 0 v(t)=t+t 1234561 Time (in hours)
