Amir ran 26.2 miles in 5 hours. On average, how many miles did he run per hour?

The answer to the problem is 5.24 and here's why:

If Amir ran 26.2 miles in 5 hours, then in order to find his average number of miles run in an hour, we have to divide the total distance by the time it took him to reach that distance. In this example, his total distance was 26.2 miles, and he ran it in 5 hours, so we would divide 26.2 by 5 (26.2 / 5 = 5.24), and when we do that, we get 5.24 miles per hour.

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497
