Answer:
105 mph
Step-by-step explanation:
Let's first make the problem easier by converting 1.5 hours to just one hour. 60 / 1.5 = 40. Now we have "Lily can travel 40 miles in 1 hour". That sounds much easier to solve. The problem wants us to solve how far Lily can travel in her vehicle in 3 hours with a reduced speed of 5 mph. Without the speed reduction, Lily can approximately travel 120 miles as: 40 x 3 = 120. Now putting the (5 mph) speed reduction into our equation, we have the final simplified equation: ( 40 - 5 ) x 3 = 35 x 3 = 105 mph. In conclusion, Lily can travel 105 miles per hour in just 3 hours.
