Question

The speed of a car is 60km/hr. another cars speed is 15m/s. which car is faster?by how much?​

Answer 1

Answer:

First car is travelling faster by 6 km/hr

Step-by-step explanation:

1 m/s = 18/5 km/hr

15 m/s = 15 × 18/5 km/hr = 3 × 18 km/hr = 54 km/hr

Clearly 60 > 54. So First car is travelling faster with 60 km/hr.

Difference in speeds = (60-54) km/hr = 6 km/hr

Answer 2

Answer:

Speed of 1st Car = 60km/hr

Speed od 2nd Car = 15m/s = 54,000 m/hr

= 54km/hr

So, Speed of Car 1 is more by 60 - 54 = 6

km/hr

Ans - Speed of Car 1 is more tha Car 2 by 6km/hr.

Step-by-step explanation:

we will convert second to hour

15/second = 15×(60×60)/60×60 seconds

540,400 speed per hour

we subtract 540,00-60

so Car b speed is more then car a speed by 539,940 km
