Answer:
Answer - 4 first , find how much distance does the bus travel in 15 minutes , that is 10 kms
And then find the distance travelled in 1 hour , that is , 60/15 = 4
4 × 10 kms
= 40 km/h
Answer - 5 distance between two towns = 240 kms
Speed of car = 60 km/h
Time taken by car to reach the second town = speed / distance
= 240/60
= 4 hours

distance = 30 km
speed = speed
time = 45 minutes ( convert the minutes into hours ) = 45÷ 60 = 3 /4 hrs
speed = distance ÷time
speed = 30 ÷ 3/4
= 30×4/3 = 40 km/hr
