Stewart was most recently Professor of Mathematics at McMaster University, and his research field was harmonic analysis. distance(d) equals rate(r) times time(t) or d=rt;r=d/t and t=d/r Let S=average speed on this trip S=(Total distance travelled)/(Total time required) (Note: Here's another problem that sort of underscores what average speed For the first half of the distance, she travels at 30 miles per hour. He did research at the University of London and was influenced by the famous mathematician George Polya at Stanford University. http://www.algebra.com/algebra/homework/word/travel/Travel_Word_Problems.faq.question.102118.html

Lothar Redlin grew up on Vancouver Island, received a Bachelor of Science degree from the University of Victoria, and a Ph.D. By using the formula rate(time)=distance, you can find that the time spent at 30 mi/h is 2 h and the time spent at 60 mi is 1 h; therefore, the total I had 3 hours of calc tonight so my brain is mush. SOLUTION: A driver sets out on a journey.

For the first half of the distance she drives at a leisurely pace of 30 mph, she drives the second half at 60 mph. You can only upload photos smaller than 5 MB. So total distance (d)=d1+d2=2d1 (or 2d2) Let t=total time required Let t1=time to travel the first half and this equals d1/30 Let t2=time to travel the second half and this equals You can only upload a photo (png, jpg, jpeg) or a video (3gp, 3gpp, mp4, mov, avi, mpg, mpeg, rm).

So, 120 miles are traveled in 1+2 = 3 hours -> avg speed is 120 miles / 3 hours = 40 mph. Et harum **quidem rerum facilis est et expedita** distinctio.

## This means it will take you one hour.

Hard drive full? YOU ARE ON THE RIGHT TRACK!!!! By dividing the total distance (120 mi) by the total time (3 h), you can derive the average speed (40 mi/h).

For the second half of the distance, she travels at 60 miles per hour. Over 6 million trees planted anonymous 4 years ago Where do I start? Total miles driven / total time taken = average speed Total time taken is \[\frac{D}{30} + \frac{D}{60} = \frac{2D}{60}+\frac{D}{60} = \frac{3D}{60}\] Average speed = total miles/ total time = \[\frac{2D}{(\frac{3D}{60})}\]but dividing Et harum quidem rerum facilis est et expedita distinctio.

He also taught at The Pennsylvania State University. Thanks !? For the first half of the distance, she travels at 30 miles per hour. from McMaster University in 1978.
