The distance between two cities is 1900 km. how long will it take, in h, to drive from one city to the other if your average speed is 84 mi/h?

14 hours

Step-by-step explanation:

from the formular;

speed = distance / time

time = distance / speed

distance = 1900km

speed = 84 mi/h

we have to change this to km/h since our distance is in km

1 mile = 1. 609km

84mile = x

cross multiply

x = 84 × 1. 609

x = 135. 156km

speed = 135. 156km/h

Time = distance / speed

time= 1900 / 135. 166

time = 14. 058

time = 14 hours approximately

Therefore it takes 14 hours to drive from one city to the other.

step-by-step explanation

e2020 got it right

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
