Question

What distance will be covered by a bus moving with a speed of 72km/hr in 30 sec ?​

Answer 1

Given :

• Speed is 72km/hr = 20 m

• Time taken = 30 seconds

To Find :

• Distance covered by the bus = ?

Solution :

Formula to be used :

• Distance = Speed × Time

It's given :

• Speed = 20 m
• Time = 30 sec

Putting the values,

→ Distance = Speed × Time

→ Distance = 20 × 30

→ Distance = 600 m

Hence,

• Distance covered by the bus is 600 m

Speed

• Distance covered by the object in unit time is called as speed.

Formula for finding the average speed when distance and time are given :

• Average speed = Distance / Time

Formula for finding the time when distance and speed are given :

• Time = Distance ÷ Speed

✯ Appropriate Question ✯

• ➠ What distance will be covered by a bus moving with a speed of 72km/hr in 30 sec ?

✯ Required solution ✯

• ➠ Speed is defined as the ratio of distance covered to the time taken to cover the distance.

• ➠ S=d/t;=>d=S*t

• ➠ Given S= 72kmph

• ➠ 1km=1000m

• ➠ 1hr=3600 sec

• ➠ For 1 sec :t=1 sec

• ➠ d=s=72/3600=0.02km=20m

• ➠ For 30 sec:t=30 sec

• ➠ d=20*30=600 m.

✦ Distance covered = 600 m✦
