Question from Abigaíl, a student: Romeo and Juliet live 40 miles apart. Romeo jogs 8mph, while Juliet "fast walks" at 4mph. They leave their houses at the same time and journey toward each other. I have totally forgotten how to solve this type of problem. Help? |
Hi Abigaíl,
Romeo jogs at 8 mph and Juliet "fast walks" at 4 mph. When they start they are 40 miles apart. How fast is the distance between them decreasing? At this rate how long will it take for the distance to decrease to 0 miles? At 40 mph how far will Romeo walk in this time?
I hope this helps,
Penny
