You would have to make the numbers have the same denominator. So you would have -15/20 + 4/20
Then you would have to put the sign of the higher number on it, So you would have -15/20 + 4/20 = -11/20
Answer: 2 2/5
Step-by-step explanation:
You can do 6 * 2/5 = 2 2/5
OR
You can do 2 + 2 + 2/5
6/5 = 1 1/5 * 2 = 2 2/5
Step-by-step explanation:
First we need to get his speed:
speed = distance / time
If he travelled 24 miles in 20 mintues, his speed is 24 / 20 = 1.2 miles per minute
If he travelled 18 miles in 15 minutes, his speed is 18 / 15 = 1.2 miles per minute
Those two should give us the same answer since it says that the distance varies linear with time, which means that his speed is constant.
Then after 30 minutes he will have traveled: 1.2 x 30 = 36 miles
