Can you help me solve this problem? Cuz i cant seem to figure it out.
An orbiting satellite traveled 3,225 miles in 40 minutes. Find its speed in miles per hour. (Round your answer to the next whole number.)
(a)103 (b)4,838 (c)4,267 (d)6,200 (e)150

Use a proportion. Cross multiply and solve for x.
3225/40 = x/60
40x = 193,500
x = 193,500 / 40
x = ?
