jason leaves detroit at 2 pm at a constant speed. he passes ann arbor, 40 mi. from detroit, at 2:50 pm.
express the distance traveled in terms of time elapsed.
i know d=rt. t=50 min. d=40 mi. does that mean the r= 4/5 mi/min. ? but how would u get the answer from there?
I think they want d=(4/5)t, but I'm not sure. You could put t on the x-axis and d on the y-axis and have a line with slope 4/5 which corresponds to the rate. Aside from that, the question is not clearly stated in my opinion.
You are correct in using the formula d = rt, where d represents the distance traveled, r represents the rate or speed, and t represents the time elapsed.
In this case, you have been given the value for d (40 miles) and t (50 minutes). Your calculation of r = 4/5 miles per minute is correct.
To express the distance traveled in terms of time elapsed, you would write the equation as d = (4/5)t.
In order to get the answer, you would need to input a specific value for t (time elapsed) into the equation. Let's say you want to find the distance traveled after 1 hour, or 60 minutes. You would substitute t = 60 into the equation:
d = (4/5)(60)
d = 48 miles
Therefore, after 1 hour (60 minutes), Jason would have traveled a distance of 48 miles.
