Question

An arrow can travel at a speed of 648 km/h. How long does the arrow take to travel a distance of 2400 m?

Answer 1

Answer:

we know that Time = Distance /speed

Step-by-step explanation:

so,

speed =648km/h

distance =2400 m

first we have to convert 2400 m into km

for this we have to do 2400÷100=24 km

then,

time =distance / speed

24km/648km/h

2.22min

it will reach in 2.22mim

Answer 2

Answer:

The answer is shown please see.

And the answer is 1 whole and 1by 3 is the answer.

See the step by step solution.

Step-by-step explanation:

$speed \: of \: the \: arrow \: = \: 648 \: km \: per \: hour \: \\ = \: 648 \times \frac{5}{18} \: metre \: per \: second \: \\ \\ = \: 180 \: metre \: per \: second \: \\ time \: taken \: by \: the \: arrow \: to \: cover \: the \: distance \: of \: 2400 \: m \: \\ = \: \frac{distance}{speed} \: \\ = \: \frac{2400}{180} seconds \: \\ 0 \: will \: be \: simplified \: and \: 240 \: will \: be \: simplified \: by \: 12 \: and \: 180 \: by \: 9. \\ = \: \frac{12}{9} \: seconds \: \\ 12 \: will \: simplified \: by \: 4 \: and \: 9 \: will \: be \: simplified \: by \: 3. \: \\ = \: 1 \frac{1}{3} \: answer \:$
