You can put this solution on YOUR website! dominic rode his motorbike 20 min to helen's house, and then the two drove in a car 30 min to a beach 35 mi from dominic's home. if the car speed was 10 mi/h faster than that of the motorbike, how fast did the car travel?
----------------------
m = speed of the motorbike
---
m*20/60 + (m+10)*30/60 = 35
m/3 + (m+10)/2 = 35
2m + 3m + 30 = 210
5m = 180
m = 36
car speed = 46
