BRAINLIEST if you get it right... Calculate, A driver travels 55 km in 1 hour. He then drives at a speed of 35 km/h for 2 hours. Next, he drives 175 km in 3 hours. What was his average speed?

average speed = (55 + 70 + 525) / 6

= 650 / 6

= 108.33 km per hour

Step-by-step explanation:

first hour = 55 per hour.

= 55

second and third = 35 per hour.

= 70

fourth, fifth and sixth = 175 per hour.

= 525

average speed = (55 + 70 + 525) / 6

= 650 / 6

= 108.33 km per hour

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

it would rotate about 180 degrees.
