Question

Convert the answer to minutes and seconds.

5 minutes = ___ seconds

Sadie had 1/8 minutes and ___ seconds for question C.

A) 240, 15
B) 300, 15
C) 250, 30
D) 200, 20

Answer 1

To convert 5 minutes to seconds, we multiply by 60 to get 300 seconds. When converting 1/8 minute to seconds, we multiply by 60, resulting in 7.5 seconds, which is rounded to 8 seconds. The correct answer is Option B, when rounding to the nearest whole second.

Step-by-step explanation:

To convert 5 minutes to seconds, we multiply the number of minutes by 60, since there are 60 seconds in 1 minute:

5 minutes × 60 seconds/minute = 300 seconds

Sadie had 1/8 minutes which we need to convert to both minutes and seconds. To find 1/8 of a minute in minutes and then in seconds:

1/8 minute = (1/8) × 60 seconds = 7.5 seconds

Since there are no fractions of a second in the answer choices, we have to round to the nearest whole number giving us 8 seconds.

The correct answer is B) 300, 7.5 which is rounded to 300, 8.
