Question

A car is driving west on a highway at 25 m/s. what is the car's speed in km/h?

Answer 1

90 km/hr

Unit conversion 1000 m/km 60 min/hr 60 s/min

Answer 2

Answer: The speed of car is 90 km/hr

Step-by-step explanation:

We are given:

Speed of car = 25 m/s

To convert this speed into km/hr, we use the conversion factors:

1 km = 1000 m

1 hr = 3600 s

Converting the speed into km/hr, we get:

`\Rightarrow ((25m)/(s))* ((1km)/(1000m))* ((3600s)/(1hr))\\\\\Rightarrow 90km/hr`

Hence, the speed of car is 90 km/hr
