A car travels for 18 minutes at an average speed of 72 km/h. (a) How far will the car travel in these 18 minutes?
appel

~21.6 miles

Step-by-step explanation:

72:1 is 72mph

18 min is 30% of a hour

72 times .3

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)
