Answer:

45 3/10 miles per hour

Step-by-step explanation:

Distance travelled by the car = 30 1/5 miles

Time taken = 2/3 of an hour

Average speed = distance travelled / time taken

= 30 1/5 miles ÷ 2/3 of an hour

= 151/5 ÷ 2/3

= 151/5 × 3/2

= (151 * 3) / (5 * 2)

= 453 / 10

= 45 3/10 miles per hour

Average speed = 45 3/10 miles per hour
