A bus covers 270 km distance in 6hrs i) Find the speed of the bus in the km/per hr ii) how many kilometer does it travel in 9hrs at the same speed? (Unitary method)

Distance=Speed×Time

When speed is 40 kmph

Distance traveled by car =40×9

                                         =360 km

When speed is 60 kmph

Time taken to complete the journey =  

60

360

                                                            =6 hours

270 ÷ 6 = 45

45 x 6 = 270

45 x 9 = 405

The answer is 405

Hope it helped❤️

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
