George rode the 27 miles to town in 2 hours. he reduced his speed by 10 miles per hour on the return trip. how long did the return trip take? (a)1.15 hours (b)7.71 hours (c)2.74 hours (d)1.26 hours

Step-by-step explanation:

If he rode 27 miles in 2 hours then that means he rode 13.5 miles in 1 hour because 13.5 is half of 27. This also means that he was moving at 13.5 mph. He reduced his speed on the return trip by 10 mph so, 13.5 - 10 = 3.5. Now that we know he was going 3.5 mph on the return, we can multiply 3.5 by 7.71 to get 27 since that's how far the ride was. 3.5 x 7.71 = 26.985. It's not exactly 27 but it's a lot closer than the rest.
