Answer:
17.5 miles per hour
Step-by-step explanation:
A boat travels upstream on a Mississippi river for 3.5 hours
The return trip takes 2.5 hours
The boat travels 2 miles per hour faster downstream
Let y represent the speed that was travelled upsteam
3.5y = 2.5(y + 2)
3.5y = 2.5y + 5
3.5y - 2.5y = 5
y = 5
Therefore the distance travelled by the boat upstream can be calculated as follows
= 3.5 × 5
= 17.5 miles per hour
Answer: rectangular pyramid
Step-by-step explanation:
Answer:
D. y = -4x - 6
Step-by-step explanation:
→ Work out gradient of line
→ Write into y = mx + c format
y = -4x + c
→ Substitute ( -2 , 2 ) into the equation to find c
2 = 8 + c
→ Minus 8 from both sides
-6 = c
→ Write full equation y = -4x - 6
