Question

A search and rescue drone can scan 0.5 hectare in 2 minutes. How many hectares per minute can the drone scan? 5/10 ha | 2 min = 5/10×2/1 yes or no

Answer 1

Drone will take 0.25 hectare per minute to scan the area.

Explanation:

By using unitary method,

A search and rescue drone takes 2 minutes to scan the area = 0.5 hectare.

Area scanned by the drone in 1 minute =
`\frac{\text{Total area scanned}}{\text{Total time taken}}`

=
`(0.5)/(2)`

= 0.25 hectare per minute

Therefore, drone will take 0.25 hectare per minute to scan the area.
