Answer:

76%, $\frac{19}{25}$ , and Likely

Step-by-step explanation:

The problem tells us that P(red) = 0.76

0.76 as a percentage is represented as 76 out of a 100 or 76%

0.76 as a fraction is $\frac{76}{100}$ which can be simplified to $\frac{19}{25}$ by dividing the numerator and denominator by 4

The probability could be considered "Likely" as it is above 50%

A biker’s speed is 1.5 times faster than a walker’s speed. They start moving simultaneously in the same direction from the same

worty [1.4K]

Let the walker’s speed be W, then the biker’s is W+1.5W=2.5W. Difference in speed is 1.5W. Distance=speed times time, so 12.5=1.5W×1.5=2.25W, and W=12.5/2.25=1250/225=50/9=5.56 mph. The biker’s speed is 2.5W=125/9=13.89 mph to 2 Dec places.
(Note: “1.5 times faster than a walker’s speed” could not reasonably mean the biker’s speed=1.5W because this would give W=16.67 mph, which is very fast for a runner, let alone a walker (!), and a biker’s speed of 25mph.)

andrey2020 [161]

I'm sorry but the solution you proposed was a bit hard to follow, so I'll just post my solution: we convert "2 and 1/2" to a single fraction:

$2+\dfrac{1}{2} = \dfrac{4}{2}+\dfrac{1}{2}=\dfrac{5}{2}$
