x pairs          x pairs        x pairs

Helena  1b +   x pairs of socks

A red ant travels 9/8 inches in 3/4 minutes and 3 3/8 inches in 2 1/4 minutes what is the ants speed in inches per minute? What
I am Lyosha [343]

Answer:

1. 1.5 inches per minute

2. 90 inches per hour

Step-by-step explanation:

speed = \frac{distance}{time}

1. total distance covered = \frac{9}{8} + \frac{27}{8}

                                      = \frac{9+27}{8}

                                      = \frac{36}{8}

                                      = 4\frac{1}{2} inches

Total time taken = \frac{3}{4} + \frac{9}{4}

                           = \frac{3 +9}{4}

                           = \frac{12}{4}

                           = 3 minutes

The ants average speed = \frac{4.5}{3}

                                         = 1\frac{1}{2}

                                         = 1.5

The ants speed is 1\frac{1}{2} inches per minute.

2. Since;

60 minutes = 1 hour

3 minutes = x hours

x = \frac{3}{60}

  = \frac{1}{60}

  = 0.05 hours

Speed = \frac{4.5}{0.05}

           = 90 inches per hour

The red ants speed is 90 inches per hour.

What is the volume of the box pictured below?
noname [10]

Answer:

\frac{3}{4} m³

Step-by-step explanation:

The volume (V) of the cuboid is calculated as

V = lbh ( l is length, b is breadth and h is height ) , then

V = 1 \frac{1}{8} × \frac{4}{5} × \frac{5}{6} ( change mixed number to improper fraction )

  = \frac{9}{8} × \frac{4}{5} × \frac{5}{6} ( cancel the 5's, 4 and 8 by 4 and 9 and 6 by 3 )

  = \frac{3}{2} × \frac{1}{1} × \frac{1}{2}

  = \frac{3}{4} m³
