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.
