Answer:
Morning's average rate = 50 mph, and Afternoon's average rate = 25 mph.
Step-by-step explanation:
Suppose he drove 150 miles for X hours, then his average rate in the morning was (150/X) mph.
Given that he spent 5 hours in driving.
And he drove 50 miles for (5-X) hours, then his average rate in the afternoon was 50/(5-X) mph.
Given that his average rate in the morning was twice his average rate in the afternoon.
(150/x) = 2 * 50/(5-x)
150/x = 100/(5-x)
Cross multiplying terms, we get:-
150*(5-x) = 100*x
750 - 150x = 100x
750 = 100x + 150x
750 = 250x
x = 750/250 = 3.
It means he spent 3 hours in the morning and 2 hours in the afternoon.
So morning's average rate = 150/3 = 50 mph.
and afternoon's average rate = 50/(5-3) = 25 mph.
<h3>Answer: C) 12</h3>
Explanation:
We have 4 options for the first choice and 3 options for the next. So there are 4*3 = 12 different combos possible. The tree diagram below shows 12 different paths to pick from. For instance, the right-most path has us pick the number 4 and the color yellow.
Answer:
Cost of selling price = $5.33 (Approx)
Step-by-step explanation:
Given:
Cost of price of cookie = $3 each
Number of cookies = 80
Damaged = 10%
Markup on cost = 60%
Find:
Cost of selling price
Computation:
Total cost of cookie = 80 × 3 = 240
Markup price = 240 + 240(60%)
Markup price = 384
Number of damage cookies = 80(10%) = 8
Remain cookies = 80 - 8 = 72
Cost of selling price = Markup price / Remain cookies
Cost of selling price = 384 / 72
Cost of selling price = $5.33 (Approx)
