Answer: 308
Explanation: because 2 days is 48 hours so multiply by 4 will equal 192 the subtract it from 500 and the answer is 308
a=annie
b=brian
a is 5 times of b and 3 means
a=5(b+3)
together travel 30
a+b=30
so
sub 5(b+3) for a
5(b+3)+b=30
distribute
5b+15+b=30
6b+15=30
minus 15 both sides
6b=15
divide boh sides by 6
b=2.5
sub back
a=5(b+3)
a=5(2.5+3)
a=5(5.5)
a=27.5
annie traveled 27.5 hours
brian traveled 2.5 hours
Answer:
1400000
Step-by-step explanation:
interest = principal x rate x time
interest = 200000 x 4 x 1.5
interest= 1200000
amount of interest = principal + interest
1200000+200000=1400000
