Brad drove from Athens to Atlanta in 1.5 hours, 72 miles away, before he flew out for Kansas City. What was his rate of speed in miles per hour

48 mph

Step-by-step explanation:

72 (miles) / 1.5 (hours)

= 48

48 mph

4

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
