Question

Two buses start at the same point and travel in opposite directions. The first bus travels 10 miles per hour faster than the second bus. In 3 hours, the buses are 282 miles apart. Use the formula below to determine the rate of the second bus. 3(r + 10) + 3r = 282

Answer 1

Hi,

Explanation:

Let's say v the speed of the second bus

v+10 the speed of the first bus

`3*v+3*(v+10)=282\\6v+30=282\\6v=250\\v=41,66...\ (mi/h)`
