Answer:
18
Step-by-step explanation:
because the number of people that can swim will be about quarter out of hundred
She drove 2 hours because when you divide 140 by 70 u get 2
The average velocity in km/h is: 34.3km/hr
<h3>What is average velocity?</h3>
Average velocity refers to speed at which the time intervals (t) change in position or displacement happens, divided by the change in position or displacement (x).
=> Average velocity = 
Now,
The time taken is missing in the question; the time taken = 18 mins =
hours.
The distance of her home to the university = 10.3 km
As, average velocity = 
=> Velocity =
= 34.3 km/hr
Hence, the average velocity = 34.3 km/hr
