It takes a person the same time to walk 10 miles as it takes a car to travel 15 miles in heavy traffic. If the car is traveling 3 mph faster than the person walking. How fast is each traveling?
The person is traveling__
mph.
The car is traveling__
mph.

The person is traveling 30 mph.

The car is traveling 45 mph.

Just mulitply 15 x 3 and 10 x 3.

Let’s break the numbers down.

10 + 5 = 15. So we can break 15 down like how you add 15.

10 x 3 = 30.

5 x 3 = 15.

Let’s add 30 and 15 together.

30 + 15 = 45.

Let’s now multiply 10 and 3.

10 x 3 = 30.

I hope this helped!

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
