Answer:
20 square inches
Step-by-step explanation:
Set width of sign to x.
Set length of sign to y.
5x=y
2(x+y)=24 inches
2(x+5x)=24 inches
12x=24 inches
width = 2 inches
length = 10 inches
Area = 20 square inches
PLEASE GIVE BRAINLIEST
Total distance between the trains = 348 miles
Total time to cross that distance by trains = 3 h.
So, sum of their speed would be: 348/3 = 116
A.T.Q,
Speed of train 1 - speed of train 2 = 22
so, two equation that has formed are:
a+b=116
a-b=22, a=b+22
Substitute that in above equation; b+22+b=116
2b= 94, b=47 & a=116-47 =69
Speed of the TRAIN IS 47 & 69 miles per hour.
