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?

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.
