Answer:
45 mph
Step-by-step explanation:
Given: Distance travelled= 330 miles
Time taken= 6 h
Lets find out speed of car drove.
Formula; [tex]Speed= \frac{Distance}{time}[/tex]
Speed= [tex]\frac{330}{6} = 55\ mph[/tex]
∴ Car´s speed is 55 mph.
As we have been informed that car´s rate of travel slows by 10 mph
∴ we have to reduce the current speed of car by 10 mph; [tex](55-10)= 45\ mph[/tex]
The new slower rate of travel is 45 mph.
