Answer: it will take 7 hours before until Carolyn catches up with Heather.
Step-by-step explanation:
By the time Carolyn catches up with Heather, they would have travelled the same distance.
Heather left the mall traveling 16 mph. Let t represent the time that she spent in travelling this distance.
Distance = speed × time
Distance travelled by Heather would be
16 × t = 16t
Then, 3 hours later, Carolyn left traveling the same direction at 28 mph. Time spent by Carolyn in travelling the same distance would be (t - 3) hours
Distance travelled by Carolyn would be
28(t - 3 = 28t - 84
Since the distance travelled is the same, then
16t = 28t - 84
28t - 16t = 84
12t = 84
t = 84/12 = 7
Answer:
Yes, she is correct

Answer:
90
Step-by-step explanation:
The total number of "ratio units" is 9+6 = 15, so each one must stand for 225/15 = 15 people. Then 6·15 = 90 people were snowboarders who bought season passes.

Answer:
165
Step-by-step explanation:
First, m<UTS=m<UTV+m<VTS by Angle Addition Postulate. Then, you substitute all the values that you provided for the angles. 15x+15=x+15+140. You then solve for x.
15x+15=x+155
14x=140
x=10
You then plug back in 10 for X in the value of m<UTS. 15(10)+15=165
