Please help me in this question​

Answer 1

Answer: (c) 16 kilometers

=========================================================

Work Shown:

Convert each mixed number to an improper fraction.

3 & 1/9 = 3 + 1/9

3 & 1/9 = 3*(9/9) + 1/9

3 & 1/9 = 27/9 + 1/9

3 & 1/9 = (27+1)/9

3 & 1/9 = 28/9

The car's average speed is 28/9 km per hour.

5 & 1/7 = 5 + 1/7

5 & 1/7 = 5*(7/7) + 1/7

5 & 1/7 = 35/7 + 1/7

5 & 1/7 = (35+1)/7

5 & 1/7 = 36/7

The time the car travels is 36/7 hours.

----------------------

We did the conversions so we can multiply the values easier.

Distance = Rate*Time

Distance = (28/9)*(36/7)

Distance = (28*36)/(9*7)

Distance = (4*7*9*4)/(9*7)

Distance = (4*4)/(1)

Distance = 16 kilometers
