You know the trip is 450 kilometres (km) long, and your little one has to stop exactly 2/3 of the way for a break. When you head back out to the car, she asks "are we there yet?" The speed limit is 100 kph, so assuming good traffic conditions, what do you respond?

6.81

Step-by-step explanation:

450 divided by .66 (.66 is the fraction in decimal form) is 6.81.

:)

maybe 6.89?

Step-by-step explanation: i think its right

1

step-by-step explanation:

it's the only multiple of both and the least

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
