Answer:

3 ft/s

Step-by-step explanation:

The rate or speed of the remote control car, v = distance/time

Now, the distance travelled by the remote control car = 4/5 of a foot = 4/5 × 1 ft = 4/5 ft and the time it takes to cover this distance is 4/15 of a second = 4/15 × 1 s = 4/15 s.

So, v = distance/time

= 4/5 ft ÷ 4/15 s

= 4/5 ft × 15/4 s

= 3 ft/s

crimeas [40]

Answer:

Faisal receives $241

Ahmed receives $482

Walid receives $723

Step-by-step explanation:

I am going to build a system of equations to solve this question.

We have that:

x is the amount that Faysal received.

y is the amount that Ahmed received.

z is the amount that Walid received.

Ahmed, Walid and Faisal made $1446 profit from selling used books.

This means that

x + y + z = 1446

Ahmed to receive double amount of Faisal

This means that y = 2x

Walid to receive triple amount of Faisal.

This means that z = 3x

So

x + 2x + 3x = 1446

6x = 1446

x = \frac{1446}{6}

x = 241

y = 2x = 2*241 = 482

z = 3x = 3*241 = 723

Faisal receives $241

Ahmed receives $482

Walid receives $723
