On a rectangular flower bed, 16 m long and 8 m wide, lawn grass occupies a fourth of the area, and the rest of the space is reserved for flowers. The car moved at a speed of 60 km / h for 4 hours, while one-sixth of the way it was moving on a dirt road, and the rest – on a highway. How many kilometers did the car drive along the highway?

1) Knowing the length and width of the flower bed, we find its area:

S = a * b.

S = 16 * 8 = 128 square meters.

Lawn grass occupies one fourth (1/4) of the area, which means flowers – three quarters (3/4) of the area.

128 * 3: 4 = 96 or

128 * 0.75 = 96 square meters is the area occupied by flowers in a flower bed.

2) Find the distance that the car has traveled.

S = V * t = 60 * 4 = 240 km.

If he drove one-sixth on a dirt road and the rest on a highway, then five-sixths are on the highway.

240 * 5: 6 = 200 km traveled along the highway.
