Laura ran t minutes on Monday, and 15 more minutes on Tuesday. Record using algebra: If on Wednesday, Thursday, and Friday Laura ran as long as on Monday, and she did not run during the weekend, how many minutes did she run during the whole week?

Monday: t minutes

Tuesday: t + 15 minutes

Wednesday: t minutes

Thursday: t minutes

Friday: t minutes

Monday+Tuesday+Wednesday+Thursday+Friday= minutes ran

t+t+15+t+t+t=

5t+15 minutes

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
