Answer:

A. 3.2% faster

B. 3.3% slower

C. 103.3%

Step-by-step explanation:

In order to find this out, we need to take the differences and divide them by the comparative time. So, in the first one, we take the difference (.32) and divide it by Hines time.

.32/9.63 = 3.2%

In the second, we take the difference and divide by Bolt's time.

.32/9.95 = 3.3%

And finally, in the last one, we take Hines' time and divide by Bolt's.

9.95/9.63 = 103.3%

Bolt's time was 3.2% faster than Hines'.

Hine' time was 3.3% slower than Bolt's.

Hine' time was 103.2% of Bolt's.

What are percentages?

Percentage can be described as a fraction out of an amount that is usually expressed as a number out of hundred. The sign used to denote percentages is %.

What are the percentages of Bolt's time and Hine's time?

  • Difference between Bolt and Hines times = (9.63 - 9.95) / 9.95 x 100 = 3.2%
  • Percentage that Hine was slower = ((9.63 - 9.95) / 9.63 x 100 = 3.3%
  • Percentage of Hines time to Bolt's time = (9.95 / 9.63) x 100 = 103.3%
