Question

A train covers a distance of 820 km with a speed of 80 km/h. How long does it take to finish the journey?​

Answer 1

ɢɪᴠᴇɴ :-

• Distance (d) = 820 km
• Speed (s) = 80 km/h

ᴛᴏ ғɪɴᴅ :-

• Time taken (t)

sᴏʟᴜᴛɪᴏɴ :-

We know that,

→ Distance = Speed × Time

→ D = s × t

So we get ,

→ 820 = 80 × t

→ t = 820/80

→ t = 82/8 = 41/4 h

Hence,

• Time taken by train = 41/4 h

Answer 2

GIVEN

A train covers a distance of 820 km with a speed of 80 km/h.

TO FIND

How long does it take to finish the journey?

SOLUTION

• Distance travelled by train = 820km
• Speed of train = 80km/h
• Time taken to finish journey = ?

Apply formula

→ Time = Distance/speed

→ Time = 820/80

→ Time = 41/4 h

Hence, time taken to finish journey is 41/4h
