Problema Solution
A hurricane Is 300 miles offshore and moving at 50 mph for what range of time will the hurricane be between 50 and 150 miles offshore
Answer provided by our tutors
let 't' be the time in hours
since speed = distance/time => distance = speed*time
50 <= 300 - 50t
300 - 50t <= 150
by solving we find
3 <= t <= 5
