-15+5x= 20
5x= 35
x= 7
20= -15+5x
35= 5x
7 = x
60 miles per hour
distance=rate times time
first part
rate=60mph
time=3h
distance=60mph times 3h=180 miles
part 2
time=2 hours
rate=70mph
distance=70mph times 2h=140miles
total is 180mi+140mi=320miles
Step-by-step explanation:
The diameter is . . .
d = 2r
d = 2 × 5inch
d = 10 inch
The radius is . . .
r = 5 inch
The circumference is . . .
C = πd
C = 3,14 × 10 inch
C = 31,4 inch
