Answer: 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.

6/7 divided by 2 <br><br> IN FRACTION<br><br> EXPLAIN HOW U GOT
gladu [14]

Answer:

3/7

Step-by-step explanation:

First, when dividing 6/7 by 2 you need to change the number 2 into a fraction. The number 2 as a fraction is 2/1. However, this is division so you need to reverse the fraction so it is 1/2 instead of 2/1. So, 6/7 x 1/2 = 6/14. You can simplify to get your the answer.

Hope this helped!
