alondra pose la question : Ricky went on a bike ride. After 6 miles he got a flat tire and had to jog home. He jogs 3mph slower than he bikes, so the jog took 1 hour longer than the bike ride. At what rate did he travel each way? Penny Nom lui répond.
Bill pose la question : At time t=0 a jogger is running at a velocity of 300 meters per minute. The jogger is slowing down with a negative acceleration that is directly propotional to time t. This brings the jogger to a stop in 10 minutes.
a) write an expression for the velocity of the jogger at time t.
b) what is the total distance traveled by the jogger in that 10-minute interval.
