OH MY GOSH PLEASE HELP ME PLEASE HELP ME I KNOW YHIS IS EASY BUT IM STUPID AND I DONT KNOW HOW TO DO IT THANKS IF YOU ANSWERED (
ale4655 [162]
I will help you on two conditions:  1) that you never again call yourself "stupid," and that you ask no more than 1 or 2 questions per post.

I'll focus on #5.  Recall that distance = rate times time:  d = r*t.

You want distance and are given rate and time:  rate 1.8 km/min; time 48 min.

I see you write "distance" next to "1.8 km;" that is not correct, because

the problem states that "the rate is 1.8 km per minute."  1.8 km is a distance; 1.8 km / min is not (it's a rate).

So, again, to find the distance traveled, mult. the rate by the elapsed time:
 
distance = (1.8 km/min)(48 min) = 86.4 km, or about 54 miles.
