Answer:

a = 1, b = 3.

Step-by-step explanation:

a + b = 4

a - b = -2     Adding to eliminate b:

2a = 2

a = 1

So 1 + b = 4

giving b = 3.

Ana and Belinda both start down a trail at the same time. Belinda rides her bike at a speed of 10 miles per hour. It takes Belin
dolphi86 [110]

If in one hour Belinda can go 10 miles that means in 30 minutes she can go 5 miles. 60/2=30  10/2=5

If she can go 5 miles is 30 minutes than by doing some simple math she must be able to go 2.5 miles in 15 mins. 30/2=15  5/2=2.5

Meaning that when you add 30+15 you get 45 and when you add the distance she can go in each amount of given time 5+2.5 you get 7.5

  • So the trail has to be 7.5 miles long
