Anybody help? Jessica drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 6 hours. When Jessica drove home, there was no traffic and the trip only took 4 hours. If her average rate was 22 miles per hour faster on the trip home, how far away does Jessica live from the mountains? Do not do any rounding.
The distance each way must be equal. d = rate times time Let r equal rate,r=rate 6r = 4(r+22) solve for r, then calculate distance.
R= 44?
How do I find the distance now?
Was I correct?
Yes, rate is 44 going to the mountains and 44 + 22 or 66 going home. It took her 6 hours to go to the mountains distance would be (d=rt) or 6 times 44. or using information going home 66 times 4 regardless they should be equal.
