Answer:
2475 cm
Step-by-step explanation:
We are given that Roberto's toy car travels 40 cm/sec at high speed and 25 cm/sec at low speed.
We have to find that the distance would have the car traveled
Speed of car at high speed=40 cm/sec
Speed of car at low speed=25 cm/sec
If car takes time to travel at high speed=30 seconds
If car takes time to travel at low speed=51 seconds
Using this formula
Distance traveled by the car at high speed=
Distance traveled by the car at low speed=
Total distance traveled by the car =1200+1275=2475 cm
Hence, the distance would have traveled by the car=2475 cm

Answer:
See attached diagram
Step-by-step explanation:
Graph the solution of the inequality First, draw the dotted line
(dotted because the sign of the inequality is <). Then determine wich part of the coordinate plane should be shaded. Since the origin's coordinates satisfy the inequality, then this point should belong to the region (red part on the diagram).
Graph the solution of the inequality First, draw the solid line
(solid because the sign of the inequality is ≥). Then determine wich part of the coordinate plane should be shaded. Since the origin's coordinates satisfy the inequality, then this point should belong to the region (blue part on the diagram).
The intersection of both regions is the solution of the system of two inequalities.
