Consider lines ℓ = {(x, y)|〈x, y〉 = 〈1,1〉 + t〈1, −2〉} and m = {(x, y)|〈x, y〉 = 〈1,1〉 + t〈−1,3〉}.
a. what is the solution to the system of equations given by lines ℓ and m?
b. describe what happens to the lines under the transformation a = 1
2 1

c. what is the solution to the system of equations after the transformation?

b.my answer is b.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
