Question

An airline ticket states that the flight takes 2 hours and 45 minutes. The flight time is actually 2 hours and 54 minutes. What is the percent error in the flight time?

Answer 1

Explanation:

Question asked:

What is the percent error in the flight time?

Solution:

As we know:

Theoretical value = 2 hours and 45 minutes

1 hour = 60 minutes

2 hours 45 minutes = 60 2 + 45 = 120 + 45 = 165 minutes

Experimental value = 2 hours and 54 minutes

1 hour = 60 minutes

2 hours 54 minutes = 60 2 + 54 = 120 + 54 = 174 minutes

Thus, the percent error in the flight time is 5.45%

Answer 2

5.45%

Explanation:

Given:

An airline ticket states that the flight takes 2 hours and 45 minutes.

The flight time is actually 2 hours and 54 minutes.

Question asked:

What is the percent error in the flight time?

Solution:

As we know:

`Percent\ error=(Experimental\ value - Theoretical\ value)/( Theoretical\ value)} *100`

Theoretical value = 2 hours and 45 minutes

1 hour = 60 minutes

2 hours 45 minutes = 60
`*` 2 + 45 = 120 + 45 = 165 minutes

Experimental value = 2 hours and 54 minutes

1 hour = 60 minutes

2 hours 54 minutes = 60
`*` 2 + 54 = 120 + 54 = 174 minutes

`Percent\ error=(174-165)/(165) *100\\ \\ Percent\ error=(9)/(165) *100\\ \\ Percent\ error=(900)/(165) \\ \\ Percent\ error=5.45`

Thus, the percent error in the flight time is 5.45%
