At exactly 5 p.m., Alex rode off from Asteroid. One hour later, Jessica rode off from Asteroid in the opposite direction at a speed 400 kph less than that of Alex. If they were 7900 km apart at 11 p.m., how fast did each travel?(adsbygoogle = window.adsbygoogle || []).push({});

Answer in the form: Alex, Jessica

Okay, my teacher says i got this problem WRONG but he won't help me figure it out.

This is what i did.

------------------------------------------

Answer: 5900, 5500

5,900 X 6(5 pm to 11pm is 6 hours = 35,400

5,500 x 5(6pm to 11pm is 5 hours) = 27,500

35,400 - 27,500 = 7,900

--------------------------------------------

What am i suppose to do instead?

And if anyone has any extra time. How do i solve this one?

Prince Henry and Princess Clay were 63 miles apart at dawn. Prince henry began the journey to the meeting place at 7 a.m. at 3 mph. Three hours later, Princess Clay went out to meet him. If they met at 4 p.m., how fast did each travel?

(I'm mostly curious about the first one :uhh: )
