Answer:
180
Explanation:
If we already know that 150 miles are covered in 2.5 hours, we can find the distance covered in one hour by dividing 150 by 2.5, which is 60. Now, we do 60 x 3 since we want to find the distance it would cover in 3 hours, so the answer is 180.
I hope this helped, if it is incorrect, I would be glad to revise my answer :)
