<h3>Given :</h3>
<h3>To find:</h3>
<h3>Step by step expansion:</h3>
write the equation
Add y/n with y/n and we will get Lcm as mn
Cancel the similar terms
remove 1 as denominator
take y as common
transfer y to other side as denominator of p
reciprocal the whole equation
transfer p other side as numerator
0.4x30 +3= 15
700/15= 46...
46x30=1380
46x15=690
700-690=10
10/0.4=25
25+1380=1405(ans)
Plane A 520 feet vertical rise 40 feet/min
plane B 3800 feet vertical dip 120 feet per minute.
vertically the speeds are 40 feet / minute & 120 feet /minute.
120 + 40 = 160 feet per minute.
the distance between them = 3800 -520 =3280 feet
t= d/r
3280/160
t = 20.5 minutes. they will be at the same altitude.
Answer:
459
Step-by-step explanation:
2 1/4 = 18/8 = 18 ft
3 3/16 = 25.5/8 = 25.5 ft
18 * 25.5 = 459
