Question

A bus travels 120km in 5 hours between two station. Find out the average speed. Convert km/hr to m/sec.​

Answer 1

Given:

• Distance travelled by bus = 120m/s
• Time taken = 5 hrs

To find:

• Average Speed

Conversion:

120 km → m

1km → 1000 m

For 120km → ?m

Now,

120km = 120 × 1000

→ 120km = 120000 m

______________________

5 hrs → min → sec

1 hr = 60 min

5hrs = 5 × 60

5hrs = 300min

Now,

min → sec

→ 300min = ? sec

1 min = 60s

→ 300min = 60 × 300

→ 300 min = 18000s

Solution:

Average Speed = total distance/total time taken

→ Avg. Speed = 120000/18000

→ Avg. Speed = 120/18

→ Avg. Speed = 6.66 m/s

Hence, average Speed of bus = 6.66m/s

Answer 2

Answer:

34.28 km/h

Explanation:

total distance/ total time

120÷90 +120÷30

240 km÷7 hrs

=34.28 km / h
