Question

. A bus starts at 8:30 a.m. from bus stop and reach the second bus stop at 8:50 a.m.

which is 20 Km away. Calculate the speed of bus and express it in (i) Km/h, (ii) m/s, and

(iii) Km/min.​

Answer 1

Answer:

the bus travels 1m / km

so the answers are

1.60 km/h

2. idk

3. 1 km/km

Answer 2

Answer

1)Time = 8:50-8:30

= 20min

We have to first convert min into hours So,

60÷20= 3 hours

Distance =20km

Speed= distance/time

So,

20/3 = 6.66 km/hr

2) Time = 20min

We have to convert this to hours-

20×60=120

Distance = 20 km

We have to convert Distance to meter so-

20x1000=20000

Speed= distance/time

Speed = 20000/120

Speed= 166.6 m/s.

3) time =20min

Distance = 20 km

So,

Speed = 20/20= i km / min
