Question

a bus moves with a speed of 75 km/ h to cover a distance 450 m. what is the time taken for the journey​

Answer 1

Answer:

6 hours

Explanation:

time = distance /speed

=450 /75

=6

∴,time taken=6 hours

Answer 2

Answer:

Time required is 0.006 h or 21.6s

Explanation:

Speed (v) is given by

$v = \frac{d}{t}$

where d is distance and t is time.

Therefore

$t = \frac{d}{v}$

distance d = 450m = 450/1000 = 0.45km

speed v = 75km/h

$t = \frac{0.45}{75} = 0.006h \\ \\ = 0.006 \times 60 \times 60 \\ \\ = 21.6seconds$
