Answer 1

Bob is 10.1 miles away from home.

Solution:

Given that

Bob is training for a Race.

Number of miles Bob ran away from home = 14.6 miles

Number of miles Bob ran towards from home = 9.8 miles

Number of miles Bob ran again from home = 5.3 miles

Need to determine how far is bob from his home.

Let position of home = A  

First, Bob ran 14.6 miles away from his home:

Let first Bob run from A to B  

=> AB = 14.6 miles

Second, Bob ran 9.8 miles towards his home:

From B to C toward A ( home ) = BC = 9.8 miles

So AC = AB – BC = 14.6 – 9.8 = 4.8 miles

Finally bob ran 5.3 miles away from his home:

From C move to D ( away from home that is A ) = CD = 5.3 miles

So AD = AC + CD = 4.8 + 5.3 = 10.1 miles.

Hence bob is 10.1 miles away from home.
