Answer:
Step-by-step explanation:
b and c are the speeds of the boat and current, respectively.
Traveling upstream, the boat moves b-c km per hour.
Traveling downstream, the boat moves b+c km per hour.
b-c = (60 km)/(½ h) = (120 km)/h
b+c = (60 km)/(⅓ h) = (180 km)/h
Adding the equations together,
2b = (300 km)/h
b = (150 km)/h
c = (30 km)/h
1.5x - 15 dollars = x - 20 Add 15 to both sides.
1.5x - 15 + 15 = x - 20 + 15
1.5x = x - 5 They will never coincide.
1.5x-x = - 5
0.5x = - 5 Multiply by 2
x = - 10
I would check your question.
you are right it is option a
cause
Answer: 6.4 miles
Lucinda lives 0.6 miles from the Park and Angie lives 10 times as far as this.
= 0.6 * 10
= 6 miles
Stacy lives 1/10 miles further than Angie;
= 6 + 1/10
= 6.1 miles
She lives 3/10 of a mile closer than Gabriel which means that Gabriel lives 3/10 of a mile further from the park than Lucinda;
= 6.1 + 3/10
= 6.4 miles
