Anorthbound bus and a southbound bus are at a bus stop at the same time. the northbound bus returns to the bus stop every 20 minutes and the southbound bus returns to the bus stop every 25 minutes. how long will it be before both busses are at the bus stop at the same time again?

It will be after 100 minutes both buses stop at the same time again.

Step-by-step explanation:

Since we have given that

Number of minutes after which the northbound bus stops = 20 minutes

Number of minutes after which the southbound bus stops = 25 minutes

We need to find the number of minutes it will before both buses are at the bus stop at the same time again.

So, L.C.M. of 20 and 25 = 100

Hence, it will be after 100 minutes both buses stop at the same time again.

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 : )
