Answer 2

Question:-

A car drives 120 kilometres in 3 hours. Calculate the average speed, in km/h, of the car using the formula: Speed = d÷t.

`\\ \\`

To find:

• Speed of car in km/h

`\\ \\`

Given :

• Distance = 120 km

• Time = 3 house

`\\ \\`

We know:-

`\\`

`\bigstar \boxed{ \rm Speed = (distance)/(time) }`

`\\`

So:-

`\\`

`\dashrightarrow \sf Speed = (distance)/(time)`

`\\`

`\dashrightarrow \sf Speed = (120)/(3)`

`\\`

`\dashrightarrow \sf Speed = \cancel(120)/(3)`

`\\`

`\dashrightarrow \bf Speed = 40 \: kmh {}^( - 1)`

`\\ \\`

`\therefore \underline {\textsf{\textbf{Speed of car is equal to \red {40km/h}}}}`
