Kathy and Cheryl are walking in a fundraiser. Kathy completes the course in 5.4 hours and Cheryl completes the course in 9 hours. Kathy walks two miles per hour faster than Cheryl. Find Kathy's speed and Cheryl's speed in miles per hour.
Let x= Cheryl's speed
Then, x+2 = Kathy's speed
Distance = (Rate)(Time)
5.4(x+2) = 9x
5.4x + 10.8 = 9x
3.6x = 10.8
x = 3
Cheryl's speed is 3 mph and Kathy's speed is 5 mph.
- charis :)) ur welcome !
Distance is same for both
rate x time = distance
kathy rate = Cheryl rate + 2
(c+2) 5.4 = c 9. Solve for c. Cathy speed. Then Kathy speed= c+2
