im lost

Answer 3

yes

Answer 4

25mph

Answer 5

r t = d

Let r be the speed of the Prince Walter ship. This ship has a head start of 4 hours and has steamed a distance of 4r at the end of 4 hours.

Both ships will steam an additional 2 hours, the Prince Walter ship at a speed of r and the Queen Sadie’s ship at a speed of r+15. Solve the following equation for r:
{ r*4 + r*2 + ( r + 15 )*2 = 230}
r = 25 mph
