Frankie Kowalski drove his jeep for 135moles on a paved road. he decreased his speed by 25 mph when he went on a dirt road. He traveled for 40 miles on the dirt road. If frankie drove his jeep for 5 hours, what was his speed when driving on the paved road?

45 miles per hour

Step-by-step explanation:

Time taken is given by distance/speed

Let speed on paved road be x hence on dirt road x-25

Time on paved road is

Time on dirt road is

The sum of these two time is equal to five hours hence expressed as

Since speed was at a point reduced by 25, x can't be 15 hence x is 45.

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
