Question

It took the football team 5h to travel from Titletown, a total distance of 1320km . Part of the trip was by bus and the remainder by plane. The bus averaged 40km/h and the plane 600km/h . How many hours were spent travelling by bus?

a. 3 hours
b. 1 hour
c. 2 hours
d. 4 hours

Answer 1

To find out how many hours were spent traveling by bus, we can calculate the time spent traveling by plane and subtract it from the total travel time of 5 hours. The distance traveled by bus is equal to the total distance minus the distance traveled by plane. By plugging in the given values, we can solve for the time spent traveling by bus.

Step-by-step explanation:

To find out how many hours were spent traveling by bus, we need to calculate the time spent traveling by plane and then subtract it from the total travel time of 5 hours. The distance traveled by bus is equal to the total distance minus the distance traveled by plane. Since the bus average speed is 40 km/h, we can calculate the time spent traveling by bus by dividing the distance by the speed:

Distance traveled by bus = Total distance - Distance traveled by plane

Time spent traveling by bus = Distance traveled by bus / Bus average speed

Substituting the given values:

Distance traveled by plane = Total distance - Distance traveled by bus = 1320 km - Distance traveled by bus

Time spent traveling by plane = Distance traveled by plane / Plane average speed

Since the total travel time is 5 hours, we can write the equation:

Time spent traveling by bus + Time spent traveling by plane = 5 hours

Substituting the calculated values:

Time spent traveling by bus + Distance traveled by plane / Plane average speed = 5 hours

Now we can solve for the unknown variable, which is the time spent traveling by bus.
