Jolene and Samantha begin a trip from the same place at the same time. If Jolene's speed is 40 mph and Samantha's speed is 50 mph, how many hours will it take for Samantha to get 25 miles ahead

Step-by-step explanation:

Jolene speed =40 mph

Samantha speed=50mph

let x be the time Samantha needs to be ahead of Jolene

40x+25=50x

25=50x-40x

25=10x

x=2.5 hours

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
