Answer 2

Answer:

5:9

Explanation:

Given Information -

• Maximum speed= 90km/hr
• Distance covered in 10 hrs. =500km.

To Find -

• Ratio of average speed to maximum speed.

Solution -

To find ratio, we will first have to find the average speed.

Average speed is the total distance travelled in a given period of time.

Mathematically - ${\frac{total\:distance }{total\:time}}$

• $= \frac{500}{10}$

• $= \frac{50}{1}$

• Average speed=$\bold\blue{50km/hr}$

ㅤ_________________________________

Now, as we know that the average speed is 50km/hr, so, let's find the ratio of average speed to maximum speed.

• $Avg. \:Speed:Max. \:Speed$
• $\cancel{50}:\cancel{90}$
• Ratio=$\bold\red{5:9}$
