<PRE><B>Question 420788</B>
You are driving from Grand Rapids, to Detroit, MI. 
You leave Grand Rapid at 4:00pm. At 5:10pm you pass through Lansing, MI a distance of 65miles.
---
d = rt
---
t = 70 min = 7/6 hr
d = 65
Rate = 65/(70) miles/min
---
distance = 0.928571t
  
I have to write a linear equation that gives the distance in miles, d, in terms of time, t.
------ 
Let t represents the number of the minutes since 4:00pm. Then, what time will you arrive in Detroit if it is 150 miles from Grand Rapidsm MI.
---
150 = 0.028571t
t = 161.54 minutes = (161.54) = (120 + 41.54)min = 2 hr 41.54 min
---
time of arrival at Grand Rapids = 6:54 PM
