Question

could someone help me with this? i'm terrible at conversions and need this in km/h

what is 120 km/h + .20 km/m?

Answer 1

You already have the first part in km/h.
In order to find the addition of two quantities , you need both of them in the same units
So, convert the second part in km/h also.

Answer 2

minutes can be changed into hour by dividing it with 60.
So, divide the second part by 60, you will get the second part also in km/h

Answer 3

that would change it to 120 km/h +.003km/h=120.003km/h right?

Answer 4

wait. no

Answer 5

I meant, minutes is in denominator here. So, in effect you will have to multiply the second part by 60. Sorry, for the wrongful explanation above.

Answer 6

its fine. thank you for explaining what to do.

Answer 7

i do have one more question if its alright with you. i'm not to sure on what to do. i think it involves a triangle.

Answer 8

Put it forth. I will see if I can help.

Answer 9

A river flows at a speed of 12 m/s from north to south. A powerboat can move at a
constant maximum speed of 23 m/s in still water.

If the boat were headed east across the river at its maximum speed, what would the resultant velocity of the boat be?
