Rock ran 3/4 of an hour on Wednesday for a distance of 4.2 miles. On Thursday, he ran for 1 hour at the same speed he ran on Wednesday. How many miles did Rick run on Thursday

the number of miles run on Thursday is 5.60 miles

Step-by-step explanation:

The computation of the number of miles run on Thursday is shown below

Here we assume the number of miles be x

3 ÷ 4 ÷ 1 = 4.2 ÷ x

3 ÷ 4 ÷ x = 4.2

3x = 16.8

x = 5.6

Hence, the number of miles run on Thursday is 5.60 miles

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

c

step-by-step explanation:

it would be see because your formula is f(x)=6x, so 6 times 1 is 6 and you go on and the best answer is c.
