Question

A car covers 25 km in 2 hour and a motorcycle covers 5m in 2 sec. Which one is faster?​

Answer 1

Answer:

Car is faster .

Explanation:

Dist. travelled by car = 25 km

Time taken = 2hr

Speed of car = 25/2 = 12.5 km/hr

= 12.5 × 5/18 m/s

= 3.472 m/s (approx)

Dist. travelled by motorcycle = 5 m

Time taken = 2s

Speed of motorcycle = 5/2 m/s

= 2.5 m/s

Here,

Speed of car > Speed of motorcycle

Hence, Car is faster .

Answer 2

Answer: Car is faster

Explanation:

FOR CAR____

covers 25 km in 2 hours

2 x 60 x 60 sec. = 25 x 1000 m

7200 sec. = 25000 m

1 sec. = 25000/ 7200 = 3.473 m

So, Car covers 3.473 m in one sec.

FOR MOTORCYCLE_______

covers 5 m in 2 sec.

So, Motorcycle covers 2.5 m in 1 sec.

Hence, CAR IS FASTER THAN MOTORCYCLE.

Hope it helps.
