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 spe
ed is 84 mi/h?
1 answer:
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.
