Celia and Dina start at the same time from two towns 90km apart, travelling
towards each other.
Celia’s rate is 5km faster than Dina’s rate.
They met after two hours
:
let s = Dina's speed
Celia goes 5 km/hr faster, therefore
(s+5) = Celia's speed
:
When they meet their total dist is 90 km. Write a distance equation
dist = time * speed
2s + 2(s+5) = 90
2s + 2s + 10 = 90
4s = 90 - 10
4s = 80
s = 80/4
s = 20 km/hr is D's speed
then
20 + 5 = 25 km/hr is C's speed
:
:
Check this, find the actual dist each traveled
2 * 20 = 40 km
2 * 25 = 50
------------
total d: 90 km
