kathy traveled m miles in h hours and then traveled x miles in h+ 4 hours. at the same overall average rate,
Find the speed from the given information; speed = dist/time
:
s = m/h
and
s = x/(h+4)
;
how long would it take her to travel 50 miles; t = dist/speed
50%2F%28m%2Fh%29 = 50+%2A+%28h%2Fm%29 = %2850h%29%2Fm hrs
and
50%2F%28x%2F%28h%2B4%29%29 = 50+%2A+%28%28h%2B4%29%2Fx%29 = %2850h%2B200%29%2Fx hrs
