Question

Julia is taking a 20 mile trip by car if she drives for 2 hours with an average speed of 60 miles per hour how many miles will she need to drive to complete her trip

Answer 1

Julia need to drive 200 miles

She drives 2 hours at an average speed of 60 miles per hour

the distance that she complete of her trip can be calculated if we multiply 2 by 60

$2\times60=120\text{ miles}$

then we subtract 120 miles from the miles of the complete trip

$200-120=80$

She needs to drive 80 miles to complete her trip
