Question

A jet plane travels at 40.8 km at an average speed of 340 m/s calculate how long this journey took- giveyour answer to the nearest minute

Answer 1

`2\ \text{minutes}`

Step-by-step explanation:

d = Distance traveled = 40.8 km

s = Speed of jet = 340 m/s

Time is given by

`t=(d)/(s)`

`\Rightarrow t=(40.8* 10^3)/(340)`

`\Rightarrow t=120\ \text{s}`

`\Rightarrow t=(120)/(60)=2\ \text{minutes}`

The time taken to complete the journey is
`2\ \text{minutes}`.
