Exercise 21. When the speed limit was 55 mph, Bob could cover 400 miles in a day's driving. After the speed limit went up to 70 mph, how far would he go in an equivalent
day's driving? What assumptions are you making? Is it necessary to calculate the time
he spent driving?

don't know what that says sorry i can't you

step-by-step explanation:

idk what it says

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
