Question

A car travels 30 mins at a speed of 120 km/hr and 45 minutes at a speed of 150 km/hr. What is the total distance covered?

Answer 1

Answer:

The total distance covered is 172.5 km.

Step-by-step explanation:

The distance traveled is given as,

$s=vt$

Here, $v$ is the speed and $t$ is the time.

The total distance traveled is given as,

[tex]s=s_1+s_2\\ =v_1t_1+v_2t_2\\ =(120\text{ km/hr})\times(30\text{ min})\times(\frac{1\text{ hr}}{60\text{ min}})+(150\text{ km/hr})\times(45\text{ min})\times(\frac{1\text{ hr}}{60\text{ min}})\\ =172.5 \text{ km}[/tex]
