Answer:
The correct option is B.
Step-by-step explanation:
It is given that Susan drove an average speed of 30 miles per hour for the first 30 miles of a trip & then at a average speed of 60 miles/hr for the remaining 30 miles of the trip.
Time taken by Susan in first 30 miles is
Time taken by Susan in remaining 30 miles is
Total distance covered by Susan is
Total time taken by susan to complete 60 miles trip is
Susan's avg speed in miles/hr for the entire trip is
The average speed of susan for entire trip is 40. Therefore the correct option is B.

Explanation:
1/2 is the probability of flipping tails because we have one side labeled tails out of 2 sides total.
1/6 is the probability of rolling a 5, because there's one side we want out of 6 total.
The two events (flipping the coin and rolling the die) are independent, allowing us to multiply those previously mentioned fractions:
(1/2)*(1/6) = (1*1)/(2*6) = 1/12
Answer:
14 feet
Step-by-step explanation:
Let F = number of feet the child traveled in total
Convert the yards to feet by applying the rule of three,
1 yard ---------------- 3 feet
2 yards -------------- X
Hence,
2 yards = 6 feet
Now add the additional 8 feet you crawled
F = 6 feet + 8 feet
F = 14 feet
Therefore, the child traveled 14 feet in total.

Answer:
78%.
53%.
38%.
42%
Step-by-step explanation:
The sum of all the angles in a triangle is 180 degrees.
You know two angles, one 90 degrees, and the other 38 degrees. Add 90 and 38 together to get 128
Now 180-128 gets 52 degrees
Angle m is 52 degrees
