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:

Ashdown to Bridgeton

3 hr at 60 mph = 180 miles in 3 hours

Bridgeton to Carton

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

Total Trip

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.

Jem boy wants to make his 8-meter square pool into a rectangular one by increasing its length by 2m and decreasing its width by

butalik [34]

Side = 8m
He increases length by 2m and reduces width by 2m
(a.) New dimensions will be -
Length = 10m and Width = 6m
(b.) Area = length x breadth (or width)
here we will use the special product (x+y) (x-y)
length = (x+y) and width = (x-y)
area = (8+2) x (8-2)
8^(2) - 2^(2)
= 60
