Question 741050
If Jaime gets a 30 sec head start, he would've ran 300 feet already. Now in another 30 secs time, Jaime would've ran 600 feet while his dad at 450. It's getting pretty close! In another minute, Jaime = 1200 ft. while his dad = 1350 ft. Oops, too much! There's a difference of 150 ft., while there is a difference of 5 ft./s in Jaime and his dad's speeds. 150 divided by 5 = 30. Let's go 30 secs back in time. Jaime = 900 ft. while his dad = 900 ft. Hey -- they're both at 900 ft.! Also, 1 min and 30 sec has passed.


The answer is 1 and a half min.
