You need to find the distance traveled in one hour. To find this, divIf the total distance by the total time. 520/12=43.3 km an hour. Hope this helps! ;)

Answer:

v= 43.3 km/ h

Explanation:

kinematics of the car

We apply the formula for calculating the speed (v):

v =  d / t     Formula (1)

Where:

v= speed in kilometers per hour (km/h)

d: distance in meters (km)

t: time in hours (h)

Data

d=520 km

t= 12 h

Problem development

We replace data in the formula (1)

v =  d / t   = 520 km / 12 h

v= 43.3 km/h

Car speed is 43.3 km / hr
