Jack drove 325 miles in 5 hours.

How many miles per hour did Jack drive?

Jack will drive 520 more miles at the same rate. How long will it take Jack to drive the 520 miles?

Jack is going to take around 8 hours if he wants to get to 520 miles. He travels at a rate of 65 miles per hour or mph.

Step-by-step explanation:

Divide 325 by 5.

To do this step by step, divide 300 by 5 first.

The answer is 60, because 5 x 6 is 30, so just add a 0.

We still have 25 left.

25 divided by 5 is 5.

Add 60 and 5, your total is 65, so we know that he goes 65 miles an hour.

Now to get to 520 miles, just add onto 325 because we know thats our base 5 hours.

65 + 325 = 390. 390 = 6h

390 + 65 = 455. 455 = 7h.

455 + 65 = 520. 520 = 8h.

Hence our answer is; Jack will take 8 hours to drive 520 miles.

answer: 60

step-by-step explanation:

1/2a + (2/3×30)   = 50

1/2a + 20 = 50

1/2a = 30

a = 60

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
