MEDAL!!!


Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 2.4 h, and Car B traveled the distance in 4 h. Car A traveled 22 mph faster than Car B.

How fast did Car A travel?

Answer 1

do you know the relation between distance, time and speed ?

Answer 2

Uhhmm no

Answer 3

distance = speed x time

Answer 4

Ok can u show me how to get the answer plz

Answer 5

how much `distance` you had travelled depends on `speed` at which you travelled and the `time` you took to travel

Answer 6

Say speed of Car A is `s`

Answer 7

Ok

Answer 8

` Car A traveled 22 mph faster than Car B`

that means speed of carB would be `s-22`, yes ?

Answer 9

I'm guessing so

Answer 10

Car A :
speed = s
time = 2.4
distance = s*2.4

Car B :
speed = s-22
time = 4
distance = (s-22)*4

Answer 11

since both cars covered the same distance,
set the distances equal to each other and solve s

Answer 12

s*2.4 = (s-22)*4

s = ?

Answer 13

It woud be

Answer 14

distribute on the right hand side and isolate s

Answer 15

Oh wait my computer is freazzinf

Answer 16

Let try and figure it out real quick

Answer 17

take your time :)

Answer 18

s*2.4 = (s-22)*4

distribute on the right hand side, what do you get ?

Answer 19

Is the (*) sign exponents?
