Answer 2

Answer:

1) A car covers 200km in 180min.The speed of the car is -

solution:

distance = 200km

Time = 180 min= 3 hours

speed = distance/time

》speed = 200/180

》 speed = 66.6km/h

2) A bus start at 10:00 am from Agra to Delhi(distance = 200km)What is its arrival time?

Solution:

time = distance/speed

time = 200/50

time = 4 hours

the bus start from Agra at 10:00 am.And the arrive to Delhi after 4 hours .So the arrival time be 10am +hours = 2:00 pm

5) A bus takes 30 min to travel a distance of 18 km.Its speed in standard unit is

Solution:

Distance = 18km= 18000 m

Time = 30 min = 1800 sec

speed = distance/time

》speed = 18000/1800

》speed = 10 m/s
