It takes Adara 3 hours to drive from Ashdown to Bridgeton at an average speed of 60 mph.
Scrat [10]

Answer:

61.2 mph

Step-by-step explanation:

Let's first calculate the individual legs of Adara's trip in terms of both time and distance:

<u>Ashdown to Bridgeton</u>

3 hr at 60 mph = 180 miles in 3 hours

<u>Bridgeton to Carton</u>

30 miles at 70 mph:  30 miles/(70 miles/hour) = 0.429 hours

<u>Total Trip</u>

Miles = 180 + 30 = 210 miles

Time = 3 + 0.429 = 3.429 hours

Average speed is (210 miles)/(3.429 hours) = 61.25 or 61.2 miles/hour to 1 decimal point.
