Question

Bob is training for a race. Bob ran 14.6 miles away from his home. Then, Bob ran 9.8 miles towards his home. Finally, Bob ran 5.3 miles away from home. How far is Bob from his home

Answer 1

Bob is 10.1 miles away from his home....

Explanation:

1) Bob ran 14.6 miles away from his home

2) Bob ran 9.8 miles towards his home

3) Bob ran 5.3 miles away from home

Bob was 0 miles away when he started running

If he starts running from his home for 14.6 miles, you would add 14.6 miles to 0 miles. When he travels away from home we will add up the distance he travels. But when he travels towards his home we will subtract the distance he travels.

0 miles + 14.6 miles

Now subtract 9.8 miles from 14.6 miles because he is travelling towards his home.

0 miles + 14.6 miles - 9.8 miles

Now Bob runs 5.3 miles away from home, we must add 5.3 miles:

0 miles + 14.6 miles - 9.8 miles + 5.3 miles

Now solve the expression:

0 miles + 14.6 miles - 9.8 miles + 5.3 miles

= 10.1 miles

Bob is 10.1 miles away from his home....
