A train travels at a speed of 90 miles per hour. How far will it have
traveled in 3 hours?
OM) 150 mi
OB) 190 mi
09 270 mi
OD) 300 mi.

270 miles

Step-by-step explanation:

We know the formula for distance

d = rt  where r is the rate and t is the time

d = 90 mph * 3 hours

d = 270 miles

c

-by-step explanation:

it would be c

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 %
