Question

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 1

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.
