Since Mr.Reed started 4.5 hours before Mrs.Reed, he has head start of 4.5*40 = 180 miles.


Due to the difference in their rates (90-40) = 50 miles per hour,

this distance between them decreases 50 miles each hour.



Hence, Mrs.Read will catch up Mt.Reed in   =  hours = 3 hours and 36 minutes.    ANSWER
