An airplane travels at a speed of 960 km/h how for can it travel in 1 hour

Marat540 [252]

Answer:

960 km

Step-by-step explanation:

Speed = Distance/Time.

From the question, we are to find the Distance.

The formula for Distance is given as:

Speed × Time.

From the question:

Speed = 960 km/hr

Time = 1 hour

Distance = 960 km/hr × 1 hour

Distance = 960 km

Therefore, the airplane can travel for 960km in 1 hour

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

snow_lady [41]

Answer:

domain is (xo ≤ x ≤ 0.45 )

range is (xo ≤ y ≤ 8.1 )

Step-by-step 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 )
