Roberto's toy car travels at 40 centimeters per second (cm/sec) at high speed and 25 cm/sec at low speed. If the car travels for 30 seconds at high speed and then 51 seconds at low speed, what distance would the car have traveled?

Respuesta :

HIGH SPEED= 40*30=1200 cm
low speed=  25*51=1275 cm 
total= 1200+1275=2475 cm

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

[tex]Distance=speed\times time[/tex]

Using this formula

Distance traveled by the car at high speed=[tex]40\times 30=1200 cm[/tex]

Distance traveled by the car at low speed=[tex]51\times 25=1275 cm[/tex]

Total distance traveled by the car =1200+1275=2475 cm

Hence, the distance  would have traveled by the car=2475 cm
