So, the first car traveled for 9 hours.
I assume there might be a typo in your question, as you mentioned "cat" instead of "car." Assuming you meant "car," let's solve the problem:
Let
be the distance traveled by the first car (at 50 mph),
be the distance traveled by the second car (at 40 mph), and
be the time taken by the second car.
The first car went 10 miles further than the second car, so we can write an equation relating the distances:
![\[ D_1 = D_2 + 10 \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/hu44kd63k61k9koeyq7ak6sgfcdpqake2t.png)
We also know that the second car traveled for 2 hours longer than the first car:
![\[ t_2 = t_1 + 2 \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/rw2ru5dgehv94fh2sw2u7v8vuxmvnq1jgr.png)
Now, we can use the formula
to express the distances in terms of speeds and times:
![\[ D_1 = 50t_1 \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/dhqld68jrinljl7agk6aewr4jhgxse6jgu.png)
![\[ D_2 = 40t_2 \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/beesw5kwq1788mu71awlgln4hhibjfj4rt.png)
Substitute these expressions into the first equation:
![\[ 50t_1 = 40t_2 + 10 \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/v5ie51knfg5c1m7fpzoftu9idgfe6ugjw3.png)
Now, use the relationship between
from the second equation:
![\[ 50t_1 = 40(t_1 + 2) + 10 \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/ikh4yvmg0v95s5brvp6xrkm42apgz6imzz.png)
Solve for
:
![\[ 50t_1 = 40t_1 + 80 + 10 \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/sdkctdifvmx0bb78om05rkuyxk14l2am2c.png)
![\[ 10t_1 = 90 \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/idzyqp6d7x9yz03r6c3o7ugvq4xm8y1u61.png)
![\[ t_1 = 9 \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/hehlhyy934ki9t3009w8b6aklpow4vg65d.png)
