Phoebe runs at 12km/h and walks at 5km/h. One afternoon she ran and walked a total of 17km. If she ran for the same length of time as she walked for how long did she run

If correct, it should be one hour. Maybe try and solve it yourself to see if this makes sense

Step-by-step explanation:

Assume the total trip that afternoon took t hours

12(t/2) + 5(t/2) = 17 => t = 2

So she ran for 1 hour.
