Answer:
31 mph
Step-by-step explanation:
Chuck travel 124 miles in the time it takes Dana to travel 108 miles.
If Chucks rate is 4mph more than Danas, and they travel the same length in time, what is chucks speed.
:
Let s = Chuck's speed
then
(s-4) = Dana's speed
;
The times are equal, write a time equation: time = dist/speed
124/s = 108/(s-4)
Cross multiply
124(s-4) = 108s
124s - 496 = 108s
124s - 108s = +496
16s = 496
s=496/16 thus leading to Chuck's speed
