Answer:
2 km/h
Step-by-step explanation:
Let
Rate of river current = x km/h
Speed of Peter's boat = 4x km/h
He takes 15 km trip up (opposite direction)
His speed upstream = 4x - x
= 3x
His speed is 3x and distance is 15 km
Time = Distance / Speed
15/3x
= 5/x
And
Moving downstream (same direction)
Speed will be 4x + x = 5x
Distance = 15km,
speed = 5x
Time = Distance / Speed
= 15/5x
= 3/x
Total time take for trip = 4 hours
Total time take for trip = upstream + downstream
4 =5/x + 3/x
4 = 8/x
Cross product
4 * x = 8
x = 8/4
x = 2
Rate of river current = x km/h
= 2 km/h
Answer:
$300.00
Step-by-step explanation:
Since 50% means half, we can take the $150.00, and multiply it by two, getting $300.00.

Answer:
7√3
Step-by-step explanation:
To simplify a square root, look for some of its factors. You are especially looking for factors that are square numbers, or sometimes factors that repeat (repeating factors give you a square number).
√147
=√3·49 Remember 49 is a square number, you can take out its square root.
=7√3 Simplified.
You might also end up with these factors instead.
√147
=√3·7·7 Two same factors mean a square number you can take out.
=7√3 Simplified form.
1. D
2. A
3. A
