I can help you with finding the average speed of an automobile traveling 275 miles in 5 hours.
Use d=rt
distance is 275 miles and the time is 5 hours. You will be solving for the rate.
275=r(5hours)
Divide both sides by 5.
55=r
answer: 55 mph.

275 / 5 = 55 mph
Assuming a right triangle:
A = (1/2)bh
A = (1/2)(11)(18)
A = 99 cm^2

275 miles in 5 hours
Average Speed= distance/time
AS= 275/5
AS= 55 mph
Area Triangle= (base*height)/2
AT=(18*11)/2
AT=99 square cms

55 mph. S= d/t, so 275 miles /5 hours = 55mph

275miles/5hours=55miles per hour
area=height*base/2=99cm^2
