jason rod his bike 26 miles at a constant speed foe 2 hours. how long will it take him to ride 104 miles at the same speed

Find how many miles he rode for 1 hour, by dividing the distance he rode by the time he rode:

26 miles / 2 hours = 13 miles per hour.

Now divide the distance you want to find the time for by his rate:

104 miles / 13 miles per hour = 8 hours.
