nalin [4]

Answer:

X = 20.6 inches

Step-by-step explanation:

Pythagorean Theorem: $A^{2} =B^{2} +C^{2}$

A = 41.2 in, while B = 35.7 in and we are solving for C.

$41.2^{2} = 35.7^{2} +C^{2}$

$1697.44 = 1274.49 + C^{2}$

Now solve for C

$422.95 = C^{2}$

Take the square root

$20.5657482237 = C$

Rainbow [258]

Answer:

36 mins

Step-by-step explanation:

0.5 miles/6 mins = 3 miles/x mins

In order to convert the ratio from 0.5 miles to 3 miles, 0.5 was multiplied by 6. Therefore, to keep the ratio the same, 6 minutes must also be multiplied by 6 to find x. This means the answer is:

3 miles/36 mins
