Question

Faisal drives his car a distance of 40 km in half an hour, how many minutes will it take to drive 100 km?

Answer 1

75 minutes

Explanation:

To calculate the time it will take for Faisal to drive 100 km, we can use a proportion based on the given information:

`\sf (Time \; 1)/(Distance\;1)=(Time\;2)/(Distance\;2)`

Given:

• Time 1 = 30 minutes (since half an hour is equal to 30 minutes)
• Distance 1 = 40 km
• Time 2 = Unknown (we need to find this)
• Distance 2 = 100 km (the desired distance)

Substitute these values into the proportion:

`\sf (30\;min)/(40\;km)=(Time\;2)/(100\;km)`

To find Time 2, we can multiply both sides by 100 km:

`\sf (30\;min)/(40\;km)* 100\;km=(Time\;2)/(100\;km) * 100\;km`

`\sf Time \; 2 = (30 \; minutes * 100 \; km)/(40\;km)`

Solve for Time 2:

`\sf Time \; 2 = (30 \; minutes * 100)/(40)`

`\sf Time \; 2 = (3000 \; minutes)/(40)`

`\sf Time\;2=75\;minutes`

Therefore, it will take Faisal 75 minutes to drive 100 km.
