Step-by-step explanation:
Answer:
50
Step-by-step explanation:
v = the original speed of the cruise
d = 225 km the distance passed
t = d/v = 225/v the total time of the travel
v*1.5 + (v + 10)(d/v - 1.5 - 0.5) = d (using the formula distance = speed*time)
1.5v + (v + 10)(225/v - 2) = 225

Answer:
I believe it's 20
Step-by-step explanation:
I'm sorry if it's wrong, but I'm pretty sure it's correct
A : B : C = 5 : 8 : 10
A+ B = 5x + 8x = 13x
13x - 10x = 60
3x = 60
x = 20
Total = 5x + 8x + 10x = 23x
23x = 23(20) = 460 <========= answer
