Question

a train travel 72 km/h.what will be the distance in 15 sec​

Answer 1

Step-by-step explanation:

convert km/ hour into m/s by multiplying it by 5/18

so 72 km/ h = 72*5/18 = 20 m/ sec

now speed = distance/ time

distance = speed * time = 20*15 = 300 m

Answer 2

AnswEr :

• Speed = 72 km
• Time = 15 sec
• Distance = ?

★ Change Speed into m/sec

➙ 72 × $\large\tt{\frac{5}{18}}$

➙ 4 × 5

➙ 20 m/sec

━━━━━━━━━━━━━━━━━━━━━━━━

▣ Distance = Speed × Time

▣ Distance = 20 × 15

▣ Distance = 300 m
