After 2 hours, Ernie had travelled 192 miles. If he travels at a constant speed, how far will he have travelled after 5 hours?

the answer is "480"

Step-by-step explanation:

so 192 divided by 2 hours is 96 so thats 96 miles per hour then I simply do 96 x 5 hours

480

Step-by-step explanation:

Since we know that after two hours Ernie travelled 192 miles, we need to find the miles for one hour. We can find this by dividing the miles by the number of hours travelled so far. 192/2 = 96. We now know that Ernie travels 96 miles an hour. In order to calculate it for 5 hours, we need to times the 96 by 5. 96 * 5 = 480. Ernie travelled 480 miles in 5 hours.

true

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
