I have to show step by step of how I got BOTH of them.
1.) 2 bikes are 100 miles apart riding at each other at 10mph.
A fly starts at one bicycle and flies towards the other at 60 mph.
When the fly reaches the bike, he turns around and flies back. He continues doing this until they meet.
How much distance did the fly cover?
Total flown by the fly?
How much distance did he fly IF...
one bike was going 10 mph and the other was going 20 mph.
2.) On an automobile trip, Aimee Cardella maintained a steady speed for the first two hours. Rush-hour traffic slowed her speed by 25mph for the last part of the trip. The entire trip, a distance of 125 mi, took 2.5 hours. What was her speed during the first part of the trip?
