Answer:
The correct option is;
B. 50 km/h
Step-by-step explanation:
The information given in the question are;
The distance between the two cities = 140 km
The direction of motion of the first car = From A to B (left)
The direction of motion of the second car = From B to A
The time after which both cars meet = 1 hour
The time duration it takes after both cars meet for the second car to reach A = 35 minutes
The total time taken by the second car from city B to city A = The time it takes to meet the first car + The time it takes after meeting the first car to reach city A
∴ The total time taken by the second car from city B to city A = 1 hour + 35 minutes = 60 minutes + 35 minutes = 95 minutes
95 minutes = 95/60 hours = 1⁷/₁₂ hours = 1.58 hours
The speed of the second car = Distance/Time = 140 km/(1.58 hours) ≈ 88.42 km/h
Therefore, let the distance from A of the point the first car meet the second car = x
Therefore, we have;
The distance from B of the point both cars meet = (140 - x) km
Given that both cars meet after one hour, we have;
The distance travelled by the second car coming from city B, after one hour = (140 - x) km = Speed of the second car × 1 hour
88.42 km/h × 1 hour = 88.42 km = (140 - x) km
x = 140 - 88.42 ≈ 51.58 km
The distance from A of the point the first car meet the second car = x = 51.58 km
The speed of car A = (The distance from A of the point the first car meet the second car)/(Time it takes both cars to meet)
∴ The speed of the first car = 51.58 km/(1 hour)
The speed of the first car = 51.58 km/h ≈ 50 km/h (Rounding up to the nearest 10th).
Question;
A store sells boxes of juice is equal size packs. Garth bought 18 boxes, Rico bought 36 boxes and Mia bought 45 boxes.
1. What is the greatest number of boxes in each pack?
2. How many packs did each person buy if each box contained the greatest number of boxes?
Answer:
The answers to the questions are;
1. The greatest number of boxes in each pack is 9 boxes.
2. Garth bought 2 packs
Rico bought 4 packs and
Mia bought 5 packs
Step-by-step explanation:
1. Here we are required to find the Highest Common Factor, H. C. F of 18, 36 an 45
So we have which gives 1, 2, and
We therefore multiply the fractions again by 2 to get
which gives
= 2, 4, 5
Therefore 9 is the H. C. F which is the greatest number of boxes in each pack
That is the greatest number of boxes in each pack is 9
2. The number of packs each of them bought is given by
Garth bought 18 boxes with 9 boxes per pack = 18/9 or 2 packs of juice
Rico bought 36 boxes with 9 boxes per pack = 36/9 or 4 packs of juice
Mia bought 45 boxes with 9 boxes per pack = 45/9 or 5 packs of juice
