Question

A bicyclist travels at a constant speed of 18 miles per hour for a total of 27minutes. Choose the function, the domain and the range according to the situation.

Answer 1

domain is (xo ≤ x ≤ 0.45 )

range is (xo ≤ y ≤ 8.1 )

Explanation:

given data

constant speed = 18 miles per hour

total time = 27 minutes = 0.45 hour

solution

we consider here Domain number of hours = x and Range distance traveled = y

we apply here distanace formula that is

Distance = speed × time .........................1

put here value

Distance = 18 × 0.45 = 8.1 miles

and no of hours x = 0 to 0.45 hours

so here

So domain is (xo ≤ x ≤ 0.45 )

and

Distance is 0 to 8.1 miles

So range is (xo ≤ y ≤ 8.1 )
