Help, I’m stuck. Will give + 22 pts up for grabs ! Question : Eliana and Allegra both belong to A cycling club. Eliana can ride 6 mph faster than Allegra, and cover the same distance in three hours that Allegra can do in 4 hours. find the speed at which each girl can ride.

Eliana can ride _ miles per hour and Allegra can ride _ mph.

let the speed of Allegra be x mph, then speed of Elliana is x+4 mph,

time to cover distance for Eliana is 2 hours, time to cover distance for Allegrais 2.5 hours,

since they both cover the same distance you have this,

distance (of Eliana) = distance (of Allegrais ),

distance=speed x time, so we have

speed (of Eliana) x time (of Eliana) = speed (of Allegra) x time (of Allegra),

2(x+4)=2.5x,

solve for x, then substitute back for speeds for Eliana and Allegra,

Eliana's speed = 16 + 4 = 20.

Allegra's speed = 16

it would be c. predictability
