Answer:
6x - 11 feet
Step-by-step explanation:
Dale is standing (2x + 7) feet height from the base of the tower.
And the tower is given to be (8x - 4)feet tall.
We have to find the distance between Dale and the top of the tower.
Now, the distance between dale and the top of the tower = height of the tower - height of Dale = (8x - 4) - (2x + 7) = (6x - 11) feet. (Answer)
7km/ 4km per hour = 1 3/4 hours
3/4 hour = 45 minutes
Total time = 1 hour and 45 minutes.
