ten minutes after Joe started, he caught up with Jim. What was Joe's average speed?

- math -
**Steve**, Tuesday, November 29, 2011 at 12:40pmJim ran for 4 minutes at 400m/min.

his distance when Joe started was thus 1600m

Joe and Jim then both ran for 10 minutes, and Joe ended up running the same distance as Jim, who had run an extra 4000m.

If Joe's speed is x m/min, then

1600 + 4000 = 10x

560 = x

So, Jim ran 1600 + 4000 m = 5600 m

Joe ran 560m/min * 10 min = 5600 m
