Then, the bug ran from −100 to 100. What distance did it cover? If the average speed of the bug during this run was 20 units per
asambeis [7]

Answer:

200 units.

10 minutes.

Step-by-step explanation:

Distance = 100 - (-100)

= 100 + 100

= 200 units.

Speed = distance / time

20 = 200/ t

t =  200/20

= 10 minutes.

There are 2.54 centimeters in 1 inch. How many centimeters are there in 1 foot? In 1 yard? Explain your reasoning.
Dmitry [639]

1 inch = 2.54 centimeters

1 foot = 12 inch

1 inch = 2.54 cm

12 inch = 12times 2.54 cm = 30.48 cm

Answer 1 foot = 12 inch = 12times 2.54 = 30.48 cm

* we know 1 yard = 3 foot

1 foot = 12 inch

1 inch = 2.54 cm

Answer : so 1 yard = 3 foot = 3* 12 inch = 36 * 2.54 cm =91.44 cm
