The distance from Charlotte to Asheville is about 120 miles. If R.C. has two hours to make the trip, but drives 50 mph for the first 60 miles, how fast must R.C. go on the second half of the trip to reach Asheville in time?

A. 70 mph
B. 75 mph
C. 77.2 mph
D. none of these

Answer:

B. 75 mph

Step-by-step explanation:

d - distance

v - velocity

t - time

d = 120 miles

t = 2 hrs

1st 60 miles :

[tex]v = \frac{d}{t} [/tex]

[tex]t = \frac{d}{v} [/tex]

[tex]t = \frac{60}{50} [/tex]

[tex]t = 1.2 \: hrs[/tex]

[tex]t = 1.2 \times 60[/tex]

[tex]t = 72 \: minutes[/tex]

2nd 60 miles:

It took 72 minutes for him to travel the first 60 miles. To get the remaining time:

[tex]t = 120 - 72[/tex]

[tex]t = 48 \: minutes[/tex]

[tex]t = 0.8 \: hrs[/tex]

For the Velocity:

[tex]v = \frac{d}{t} [/tex]

[tex]v = \frac{60}{0.8} [/tex]

[tex]v = 75 \: mph[/tex]

Luz drives at an average speed of 60 miles per hour.
She has driven for 2 hours and has traveled a distance of 120 miles.

This situation can be represented with a linear equation written in point-slope form, where x represents the number of hours and y represents the number of miles.

A popular art teacher at a school asks a sample of students if they would be interested in taking an art class next year. Of the 30 students he ​asks, 85​% are in one of his art classes this year. Only 15​% of the students in the school are in one of his art classes this year. Will this sample be​ biased? *


​Yes, because students who are in one of his art classes this year will be more likely to take one of his art classes next year.
​No, because students who are in one of his art classes this year will be less likely to take one of his art classes next year.
​Yes, because students who are in one of his art classes this year will be less likely to take one of his art classes next year.
​No, because students who are in one of his art classes this year will be more likely to take one of his art classes next year.
