To find the time it will take for Amanda and Alexis to meet, we can set up the equation:
4 = 3.5t + 4t
Combine like terms:
4 = 7.5t
Now divide by 7.5 on both sides:
t = 4/7.5
t ≈ 0.53 hours
Therefore, it will take approximately 0.53 hours for Amanda and Alexis to meet.
Amanda and Alexis live 4 miles apart. They decide to start walking toward each other’s houses at the same time. Amanda walks at a rate of 3.5 miles per hour and Alexis walks at a rate of 4 miles per hour. How long will it take for them to meet? Round to the nearest hundredth of an hour. [Remember: D = (r)(t)]
Two boxes, one with Amanda and 3.5 m p h. To the right is the other box with Alexis and 4 m p h. Below, the boxes there is a bracket, halfway between, pointing to 4 miles.
