Question

Selected runners from a marathon were asked how many miles they could run before they started to feel tired.  The results are shown in the following histogram.How many of those runners could run greater than 5.5 and less than 7.5 miles before they started to feel tired?

Answer 1

From the given history graph, the following are the runners that could run greater than 5.5 and less than 7.5 miles before they started to feel tired.

For runners that could run greater than 5.5 but less than 6.5 miles = 4 Runners

For runners that could run greater than 6.5 but less than 7.5 miles = 4 Runners

Therefore, the total number of runners that could run greater than 5.5 and less than 7.5 miles is:

`\text{ 4 + 4 = 8 Runners}`

Therefore, 8 runners could run greater than 5.5 and less than 7.5 miles.
