Well, you haven't really stated what you want to solve for... but I'm guessing it's what speed does he walk at? Also, maybe how far away was the bike shop?
distance to bike shop = 9 miles/hr * 10 minutes / 60 min/hr = 1.5 miles
Speed of walking = 1.5 miles / 30 minutes * 60 min/hr = 3 miles/hr

Assuming you are looking for walking speed
Walking time x Walking speed = Biking time x Biking speed = Distance to workshop
Plugging the Given times and speed
30 minutes x Walking speed = 10 minutes x 9 miles per hour
Dividing both sides by 30 minutes
Walking speed =(10 minutes x 9 miles per hour) / (30 minutes )
Walking speed = 3 miles per hour
