Chapter 3: Q. 295 (page 390)

Two busses leave Billings at the same time. The Seattle bus heads west on I-90 at a speed of $73$ miles per hour while the Chicago bus heads east at a speed of $79$ miles an hour. How many hours will it take them to be $532$ miles apart?

Short Answer

Expert verified

It will take them $3.5 h o u r s$ to be $532 m i l e s$ apart.

Step by step solution

Step 1. Given Information.

Speed of Seattle bus towards West $= 73 m i l e s / h r$ .

Speed of Chicago bus towards East $= 79 m i l e s / h r$ .

Distance $= 532 m i l e s$ .

Step 2. Solving the equation.

Let the required time be $x h o u r s$

We know, $D i s \tan c e = S p e e d \times T i m e$

Distance traveled by Settle bus $= 73 t m i l e s$

Distance traveled by Chicago bus $= 79 t m i l e s$

Therefore,

$73 t + 79 t = 532 152 t = 532 t = \frac{532}{152} t = \frac{7}{2} t = 3.5$

It will take them $3.5 h o u r s$ to be $532 m i l e s$ apart.
