Question

A car travel at an average speed of 25km/h at a distance of 300km. what is the time elapsed?

An average speed of 15km/h of a motorcycle at a time of 2h. Find the distance travelled?

Answer 1

#1

`\rm \hookrightarrow \: Time=(Distance)/(Speed)`

`\rm \hookrightarrow \: Time=(300)/(25)`

`\rm \hookrightarrow \: Time=\cancel(300)/(25)`

`\rm \hookrightarrow \: Time=12h`

#2

`\rm \hookrightarrow \:Distance= Speed × Time`

`\rm \hookrightarrow \: Distance=15×2`

`\rm \hookrightarrow \: Distance=30km`

Answer 2

1) 12h

2) 30 km

Explanation:

1) Time elapsed = Distance travelled/ Speed

= 300/25 = 12h

2) Distance travelled = speed * time

= 15 * 2

= 30 km travelled
