Answer 1

he correct answer option is 300 yd/h.

Explanation:

We are given that an insect is moving at a speed of 15 feet per minute and we are to covert this unit of speed into yards per hour.

For that, we will use this unit multiplier:
`(1 yard)/(3feet)` ×
`(60 min)/(1 hr)`

`15(feet)/(min)` ×
`(1 yard)/(3feet)` ×
`(60 min)/(1 hr)`

`15` ×
`(1*60yard)/(3*1hour)`

`300(yard)/(hour)`

Therefore, the correct answer option is 300 yard/hour.

Answer 2

The speed of the insect is 2700 yard/hour

Explanation:

∵ 1 foot = 1/3 yard

∵ 1 hour = 60 minutes

∴ 15 feet = 1/3 × yard ⇒ yard = 15 × 3 = 45 yards

∴ 1 minute = 1/60 hour

∵ The insect speed = 15 feet / min

∴ The insect speed = 45 ÷ 1/60 = 2700 yard /hour
