Question

tim drives at an average speed of 80km per hour for 3 hours and 45 minutes. work out how many kilometers tim drives

Answer 1

Given:

• Average Speed = 80 km per hour
• Time = 3 hours and 45 minutes

To Find:

• Distance = ?

Solution:

Let's understand

Here,Average speed is given 80 km per hour and time is also given 3 hours and 45 minutes and we have to find distance.

We know that,

$\large{\mathfrak{\underline{\fbox{Distance = Speed × Time}}}}$

According to the question,

Firstly, we will multiply by 3 hours and after finding distance we will multiply with 45 minutes.

Now, put the value

$\sf \implies \: distance = 80 \times 3 = 240 \:km$

Now,we will find distance by 45 minutes.

As we know,

$\large\sf{\underline{\fbox{1 \:Hour = 60 \: Minutes}}}$

Now, put the values

$\sf \implies \: distance = 80 \times \frac{45}{60} \\ \\ \sf \implies \: distance = 80 \times \frac{3}{4} \\ \\ \sf \implies \: distance = 60 \: km$

Now, add the both distance

$\sf \implies \: distance = 240 + 60 = 300 \: km$

Hence, Distance is 300 km.

Additional Information:-

• Distance = Speed × Time
• Speed = Distance/Time
• Time = Distance/Speed
