Answer: Noah's speed is 20km/hr
Explanation:
Given;
Final Distance between them at 5pm =320km
Time of travel = 5pm - 1pm = 4 hours
Let x represent Noah's speed
The Ryan's speed = 3x
Total distance between them in 4hours given that they are traveling at opposite directions is.
Distance = speed × time
(x + 3x) × 4hours = 320km
4x × 4 hours = 320km
x = 320km/(4×4hours)
x = 20km/hr
Noah's speed is 20km/hr
