Answer:
A) yes
Explanation:
First section of trip: 30 miles in 40 minutes
Second section of trip: 15 miles in 20 minutes
The formula for speed is distance over time
Calculate the speeds for each section of the trip.
First:
k = d/t
k = 30miles/40minutes <= reduce fraction by 10 (30÷10 and 40÷10)
k = 3 miles / 4 minutes
Second:
k = d/t
k = 15miles/20minutes <= reduce fraction by 5 (15÷5 and 20÷5)
k = 3 miles / 4 minutes
Therefore there is a constant speed because both sections of the trip are driving at "3 miles / 4 minutes".
3 miles / 4 minutes can be also formatted as:
0.75 miles per minute.
