We can easily figure out how fast the boat is moving per hour.
35 km / 7 hours = 5 km/h
We now know that we are moving at a rate of 5 kilometers every 1 hour. We can now take our 5 km/h and multiply it by 3 hours to get our answer
5 km/h x 3 = 15 kilometers
Good luck!
Answer:
B)
Step-by-step explanation:
6 + 4*5 = 6 + 20
= 26
According to BODMAS, multiplication should be done and then addition
is given
here ,
or,
or,
or,7x²+3x-4=-4
or,7x²+3x=0
or,x(7x+3)=0
Either,x=0| Or,7x+3=0
|or,7x=-3
|or,x=
So , the solution set is S={0,-
}
In 15 hours
That or 13 hours, if we don’t include the fall back for the last one tho I highly doubt that so go with 15
