The distance (in km) travelled in h hours at a constant speed of 40 km per hour is

A speed of 45 km per hour is the same as

A bus is moving with a uniform speed travelling a certain distance in a certain time. The speed of the bus is directly proportional to the distance travelled and inversely proportional to the square root of time. It travels is 60 km in 4 hours at a speed of 40 km/h. Then find how much distance will travel in 9 hours at a speed of 44 km/h?

A bus travels at a speed of 50 km per hour to go from its origin to its destination at a distance of 300 km and travels at a speed of 60 km per hour to return to the origin. What is the average speed of the bus?

A car travels a distance of 560 km in 9.5 hours partly at a speed of 40 km h^(-1) and partly at 160 km h^(-1) . What is the distance it travel at the speed of 160 km h^(-1) ?

A boy travels a distance of 8 km at the rate of 4 km per hour , 6 km at the rate of 3 km per hour and 4 km at the rate of 2 km per hour. What is the average speed for the entire journey ?

A car is traveling at a constant rate of 45 km per hour. The distance travelled by car from 10.40 am to 1.00 pm is :

An automobile driver travels from a plain to a hil station 120 km away at an average speed of 30 km per hour. He then makes the return trip at an average speed 25 km per hour. He covers another 120 km on the plain at an average speed of 50 km per hour. His average speed (in km/hr) over the entire distance of 360 km will be
