two cars traveled equal distances in different amounts of time. car A traveled the distance in 2 hours, and car B traveled the distance in 1.5 hours. car B traveled 15 mph faster than car be what is the speed of car B

60 mph

Step-by-step explanation:

Let distance travelled by both the cars equal to d.

Also assume speed of Car A as x and speed of Car B as y

Then using distance formula,

d = 2x

Similarly for car B, d = 1.5 y

Also given that

speed of car B = speed of car A + 15

y = x+15

Hence we have 2 x = 1.5 y Or x = 0.75 y

Substitute in y = x+15 : y = 0.75y+15

0.25y = 15

y = 15/0.25 = 60 mph

Speed of car B = 60 mph

The answer is 90 I believe
