The equations y = 3x - 4 and y = 3x + 1 are linear equations
The equations have no solution
<h3>How to determine the solution of the equations?</h3>
The equations are given as:
y = 3x - 4
y = 3x + 1
Next, we plot the graph of the equations y = 3x - 4 and y = 3x + 1
From the graph (see attachment), we can see that the equations do not have a point of intersection
Hence, the equations has no solution

<u>Answer:</u>
a. 2 miles
b. Answer: 45 minutes
c. Answer: 8 miles per hour
d. Answer: 7.5 minutes per mile
<u>Explanation:</u>
Given distance = 20 miles and time taken = 150 minutes, speed = constant
a. 2 miles
Given 20 miles travelled in 150 minutes,
distance travelled in 1 minute =
so that distance travelled in 15 mins = miles
b. 45 minutes
time taken to travel one mile =
so that time taken to travel 6 miles = minutes
c. 8 miles per hour
Speed of bike = distance travelled divided by time taken
time taken in hours = = 2.5 hours
Speed in miles per hour = miles per hour
d. 7.5 minutes per mile
pace is given by time divided by distance,
so pace in minutes per mile = minutes per mile
