We know that it can travel 25 centimetres in 12 seconds. First, we break down the minute into seconds.
60/12= 5
______________________________
Now, multiply 25 by 5.
25x5=125
__________________________________
With this knowledge, we just have to convert the centimetres, to meters.

Step-by-step explanation:To convert part-to-part ratios to fractions:
Use the total number as the denominator: 6 + 8 = 14.
Use each of the ratio terms as the numerator in a fraction: ...
Reduce each fraction to lowest terms: ...
The part-to-part ratio 6 : 8 converts into the fractions:
I believe that 30.5 as a fraction is 30 and 1 half but don't take my word
Multiply the total hours by each portion:
Ally = 60 hours x 0.4 = 24 hours.
Megan = 60 x 1/4 = 60 x 0.25 = 15 hours.
Rachel and Liz = 60 hours - 24 hours - 15 hours = 21 hours total.
Rachel and Liz shared equally so 21 / 2 = 10.5 hours each.
Liz babysat 10.5 hours ( 10 and 1/2 hours).
