Question

which ratio could be used to solve the following problem? ken drives his car 800 miles in 3 days, how far will he drive in 5 days?

Answer 1

Answer:

1333.333 miles

Step-by-step explanation:

Let x = distance covered in 1 day.

Given the following data;

Distance = 800 miles

Time = 3 days

In 1 day he would cover;

1 day = x miles

3 day = 800 miles

800 = 3x

x = 800/3

x = 266. 667

In 5 days;

5x = 5 * 266.667 = 1333.333 miles

Or

Let x = distance in 5 days.

Distance in miles = time in days

800 miles = 3 days

x miles = 5 days

Cross multiplying, we have;

3x = 800 * 5

x = 4000/3

x = 1333.333 miles

Therefore, in 5 days Ken would drive 1333.333 miles.

Answer 2

Answer:

Ratio: 800:3 and 1333.35:5

Solved: 1333.35 miles

Step-by-step explanation:

Given: 800 miles in 3 days  

To find: How far will he drive his car in 5 days?  

Solution: If Ken drives his car 800 miles in 3 days, to find how many miles it will take him at the same rate, we need to divide 800 miles by 3 days  

$800$ ÷ $3 = 266.666666667$  

Simplified  

$266.67$  

Now that has been figured out, we need to multiply the result by the 5 days it will take Ken.  

$266.67$ ×  $5 = 1333.35$  

Hence, At the rate of 800 miles in 3 days, Ken will drive 1333.35 miles in 5 days.

Therefore, the ratio that could be used to solve the problem is 800:3 and 1333.35:5
