Question 2 Two trains leave the station at the same time, one heading west and the other east. The westbound train travels at 95

lianna [129]

Answer:

it will take 1.4 hours for the two trains to be 294 miles apart

Step-by-step explanation:

Let t be the time taken for each train

The westbound train travels at 95 miles per hour.

Speed of westbound train = 95

time = t

Distance = speed * time = 95 t

The eastbound train travels at 115 miles per hour

Speed of eastbound train = 115

time = t

Distance = speed * time = 115 t

both trains are 294 miles apart means the distance between both trains are 294 miles

So we add the distance of both trains and set it equal to 294

95t + 115t = 294

210 t =294

t = 1.4

So, it will take 1.4 hours for the two trains to be 294 miles apart

In , QR = 4, RS = 15, and . In , VT = 8, TU = 32, and . Are the polygons similar? If they are, write a similarity statement and

iris [78.8K]

No because the scale factors are different. You can see that QR compared to VT the scale factor is 2, but in RS and TU it's different, so they are not similar.

Car A travels 702 miles on 12 gallons of gasoline car b travels 873 miles and 15 gallons of gasoline David wants to buy a car wi

Assoli18 [71]

David should buy Car A because it covers more miles in one gallon than Car B

Step-by-step explanation:

Given

Distance traveled by Car A = $d_A = 702\ miles$

Gallons used by Car A = $g_A = 12$

Distance traveled by Car B = $d_B = 873\ miles$

Gallons used by Car B = $g_B = 15$

In order to find the distance traveled on one gallon, we will divide the total distance by number of gallons

So,

Distance traveled by Car A in one gallon = $\frac{702}{12} =58.5\ miles\ per\ gallon$

Distance traveled by Car B in one gallon = $\frac{873}{15} = 58.2\ miles\ per\ gallon$

We can see that Car A travels more distance in one gallon that is 58.5 miles per gallon

So,

David should buy Car A because it covers more miles in one gallon than Car B
