    Average speed?
    I just need guidance in this question: a bicyclist travels the first 2400m of a trip at an average speed of 10 m/s, travels the next 1000m in 70s and spends the last 200s at a speed of 8 m/s. Find the average speed of the bicyclist for this trip.

    I know S=D/T but I'm a little confused with all these number and it'd be helpful if someone helped figure it out!
