This is different from earlier problem i sent out:
While on straight road, car X and car Y are traveling at different constant rates. If car X is now 1 mile ahead of car Y, how many minutes from now will car X be 2 miles ahead of car Y if car X is traveling at 50miles per hour and car Y is traveling at 40 miles per hour?
Appreciate if you can show your solutions. Thanks.
