5. The velocity of a cyclist is represented by the equation v()=-37+16t, where t is time in minutes (0 ≤ ≤ 10) and v() is velocity in miles per hour. Assuming that his velocity increases when he goes downhill and decreases when he goes uphill, within the first 10 minutes of his ride during what time interval is he going uphill? A. Between 0 and 8 minutes B. Between 0 and 4 minutes C. Between 4 and 8 minutes D. Between 4 and 10 minutes E. Between 8 and 10 minutes
