Answer: she would catch up with Tom in 1 hour.
Step-by-step explanation:
Let t represent the time it will take for Mary to catch up with Tom.
Tom leaves his boat from a dock and travels at a rate of 25 miles per hour.
Distance = speed × time
Distance travelled by Tom in t hours is
25 × t = 25t
Ten minutes later, Mary leaves the same dock in her speedboat and heads after Tom. Converting 10 minutes to hours, it becomes 10/60 hour
Time spent by Mary is (t - 10/60) hours. If she travels at a rate of 30 miles per hour, it means that the distance that she would travel in
(t - 10/60) hours is
30(t - 10/60)
= 30t - 5
By the time she catches up with Tom, they would have covered the same distance. It means that
25t = 30t - 5
30t - 25t = 5
5t = 5
t = 5/5 = 1 hour
4 shirts can be worn with one pair of pants twice and the shoes can be paired with each outfit. So I am going to say 8 outfits.
It’s the first option, 5 + c
0.9 = -4.7 - 0.6z
0.9 + 4.7 = -0.6z
5.6 = -0.6z
z = 5.6 ÷ -0.6
z = -9.33
Solve for p by simplifying both sides of the equation, then isolating the variable.
p= - 7/3
