Answer:

61

Step-by-step explanation:

  1. 13 - 1 = 12
  2. 12 ÷ 2 = 6
  3. Put 6 and 1 together: 61

Therefore, the number is 61

Let's check:

  1. 6 × 2 = 12
  2. 12 + 1 = 13

The sum of the two digits is 13, and we got that, so we are correct. The number is 61.

Answer:

49

Step-by-step explanation:

let unit digit=x

ten's digit=y

then x+y=13

x=13-y

also x=2y+1

13-y=2y+1

13-1=2y+y

3y=12

y=12/3=4

x=13-4=9

so number =10×4+9=49

They take 5 days to drive 679 miles to Seattle, how many miles will they drive each day?
Kisachek [45]

If they take 5 days to drive 679 miles to Seattle. Then the number of miles that they drive each day will be 135.8 miles per day.

<h3>What is speed?</h3>

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

Speed = Distance/Time

They take 5 days to drive 679 miles to Seattle.

Then the number of miles that they drive each day will be

→ 679 / 5

→ 135.8 miles per day.

More about the speed link is given below.
