Question

Which among the following is the fastest above covering 10 kilometre in 10 minutes a car covering 200 km in 6 hour a car covering 40 km in 1 hour above covering 2 metre in 1 seconds

Answer 1

Answer:

(1). 10 kilometer in 10 minutes

Step-by-step explanation:

v - velocity, d - distance, t - time.

v = d / t

(1). 10 km in 10 minutes

10 minutes = $\frac{1}{6}$ hour

v = 10 ÷ $\frac{1}{6}$ = 60 km/h

(2). 200 km in 6 hours

v = 200 ÷ 6 = $33\frac{1}{3}$ km/h

(3). 40 km in 1 hour

v = 40 km/h

4). 2 meter in 1 second

2 m = 0.002 km

1 second = $\frac{1}{3600}$ h

0.002 ÷ $\frac{1}{3600}$ = 0.002 × 3600 = 7.2 km/h
