Tom ran the first 1.5 miles of a 3-mile race in 10.5 minutes. If Tom ran the entire race in 22.5 minutes, what was his average speed per mile to the nearest tenth for the last half of the race?

step-by-step explanation:

a rhombus is a parallelogram enjoying his symmetry.

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 %
