Acar travels at 40 km/h for 2 h and 60 km/h for 3 hr. what is its average speed?

ive been doing this type of stuff in my class.

so to find this you need to first:

multiply 40 * 2

and multiply 60 * 3

= 80

= 180

add 180 + 80 = 260

add the time together so 2 + 3 is 5

divide 260 / 5 = with an answer of 52km/h

i hope this helps, if incorrect or mis proper answer let me know :)
