Question

A car travels 300 miles in 10 hours at a constant rate. If the distance traveled by the car can be represented as a function of

the time spent driving, what is the value of the constant of variation, K?

O 1/30 mph

30 mph

60 mph

3000 mph

Answer 1

30 MPH ............................................................................................................

Answer 2

30 mph

Explanation:

Distance travelled=300 miles

Time travelled=10hours

At a constant rate,k

Let distance travelled=d

Time travelled=t

Then,

d=kt

300=k*10

300=10k

k=300/10

=30

k=30mph

30 miles per hour
