The initial speed of a car is 10 km/h. Every minute the speed of the car increases by 50% of the initial speed. Which graph best suits the relationship between time and speed of the car?
Time (in min) |
Speed of the car (in km/h) |
0 | 10 |
1 | 10+50% of 10=10+5=15 |
2 | 15+50% of 10=15+5=20 |
3 | 20+50% of 10=20+5=25 |
