Answer:

0.95 miles per minute

19 miles in 20 minutes

Step-by-step explanation:

To find out how many miles traveled in a minute, we will divide 57 by 60, because there are 60 minutes in an hour, and there were 57 miles traveled in a hour. This gives you the rate of miles per minute (0.95), and to get the answer for 20 minutes, just multiply 0.95 by 20 (19 miles).

Mean of the binomial distribution

μ = np

μ = 840 ×0.280

μ = 174.972

Final answer:-
