Question

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?

Answer 1

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

Answer 2

2475 cm

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

`Distance=speed* time`

Using this formula

Distance traveled by the car at high speed=
`40* 30=1200 cm`

Distance traveled by the car at low speed=
`51* 25=1275 cm`

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

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