Answer:
<em>24 minutes</em>
<em></em>
Step-by-step explanation:
Given:
Distance per lap = 2 miles
Speed of Lou Lambert = 160 miles/hr
Speed of Ralph Redding = 170 miles/hr
Speed difference between the two = 170 - 160 = 10 miles/hr
Therefore, we can say that <em>Ralph gains 10 miles in 60 minutes </em>over Lou<em>.</em>
We have to find the time in which Ralph will gain 2 laps i.e. 2 2 = 4 miles.
Let us use unitary method to find the required time.
10 miles are gained by Ralph in 60 minutes
1 mile will be gained in
4 miles will be gained in 6 4 = <em>24 minutes</em>

Answer:
answer C
Step-by-step explanation:
Answer:
It travels for 3 hours, then stops, for 1 hour, and finally travels again for 1 hour
Step-by-step explanation:
for the first 3 hours (x terms in coordinates, 0 to 3) the car is gaining miles (the y terms in the coordinates given, 0 to 42), then from hour 3 to hour 4 (1 total hour) no miles are gained (y terms 42 to 42=no change/no gain), and the the miles change again from hour 4 to hour 5 (x terms again, 4 to 5), 1 total hour
