Bert is 22 kilometers away from Brenda.
Both begin to walk toward each other at the same time.
Bert walks at 2.5 kilometers per hour. They meet in 4 hours.
How fast is Brenda walking?
:
Let b = B's walking speed
:
Write a distance equation, dist = speed * time
Both walk for 4 hrs, when they meet, the total each has walked will be 22 km
:
2.5(4) + 4b = 22
:
10 + 4b = 22
4b = 22 - 10
4b = 12
b = 12%2F4
b = 3 km/hr is B's walking speed
