A runner times his speed around a circle track with a circumference of 0.478 mi. At the start he is running toward the east and the track starts bending toward the north. If he goes halfway around, he will be running toward the west. He finds that he has run a distance of 0.750 mi in 4.00 min. What is his (a) average speed and (b) average velocity in m/s?
Please be detailed with your answers and show your calculations if possible!
Thanks a lot

They want both answers in m/s. 
Yes, I got part A correct!! Working on part B!!
if you have part a, the answer in miles per minute (the units given) then divide by 60 to get miles per second, then multiply by 1,609.3 to get meters per second
