Question 1026981: after traveling the first 480 miles in 12 hours, the traveler increased her speed by 20 miles per hour. how long did it take her to travel the last 300 miles Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! Hi there,
480 miles in 12 hours
Speed = Distance/Time
Speed = 480/12
Speed = 40mph
If she increases her speed by 20mph
she will be travelling at 60mph
Time = Distance/Speed
Time = 300/60
Time = 5 hours.
Hope this helps :-)
