Angela took 56 minutes to take her history test brian took 70% of the time that it took angela to complete the test. How long did it take brian to take the history test

39.2 minutes (39 minutes and 12 seconds)

Step-by-step explanation:

We know that Brian took 70% of the time that Angela took to complete the test, so to find how long Brian took to take the history test, we need to multiply the percentage (70%) of time from Angela's time (56 minutes):

70% of 56 = (70/100) * 56 = 0.7 * 56 = 39.2

Brian took 39.2 minutes (39 minutes and 12 seconds) to complete the history test.

Answer: 39.2 minutes

Step-by-step explanation:

Angela used 56minutes. Brain used 70% of Angela's time which will be 70% of 56.

70/100 * 56 = 39.2 minutes.

Therefore, Brian used 39.2 minutes for the test.
