Elizabeth competed in a race and found that her times for the swimming, cycling and running legs were in the ratio 3:1:2
If the quickest leg took 10 minutes, how many minutes did she take to complete the whole race?

30 mins

Step-by-step explanation:

let time for cycling be a

-> time swimming = 3*a

-> time running legs = 2*a = 10 mins -> a = 5mins

Whole time = 3*a+a+2*a = 6*a = 6*5 = 30 mins

60 mins

Step-by-step explanation:

Let the total time spent in all activities be X

So (1 divided by the total ratio ) of the total time = 10 [ because the least ratio has the shortest lap]

So total ratio = 3+1 +2=6

Therefore time spent on cycling is

1/6 * X = 10mins

X = 10 * 6 mins = 60 mins

Total time for all activities = 60mins

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
