Question

A motorcyclist travels on a

straight road at a speed
constant 85km/h. Determine the
distance recorded in 12 minutes​

Answer 1

17 km

Step-by-step explanation:

Given values:

• Speed = 85 km/h
• Time = 12 minutes

As the unit of time for speed and time is different, convert the time into hours by dividing the minutes by 60:

`\implies \textsf{Time }=(12)/(60)\; \sf =0.2 \; h`

Therefore:

• Speed = 85 km/h
• Time = 0.2 h

`\boxed{\sf Speed=(Distance)/(Time)}`

Substitute the speed and time into the formula and solve for distance:

`\implies \sf 85=(\sf Distance)/(0.2)`

`\implies \sf Distance=85*0.2`

`\implies \sf Distance=17\;km`

Therefore, the distance recorded in 12 minutes is 17 km.

Answer 2

The distance recorded by the motorcyclist in 12 minutes is 17 km.

Step-by-step explanation:

We can use the formula:

• 
  `\rm{Distance = Speed * Time}`

where:

• Distance = the distance traveled by the motorcyclist
• Speed = 85 km/h (constant speed)
• Time = 12 minutes (converted to hours by dividing by 60)

We know that 12 minutes is equal to 12/60 = 0.2 hours.

Substituting the values, we get:

• 
  `\rm{Distance = 85\: km/h * 0.2\: h}`
• 
  `\rm{Distance = 17\: km}`

`\therefore` The distance recorded by the motorcyclist in 12 minutes is 17 km.
