An airplane travels about 1500 km in a straight line between Toronto and Winnipeg. However, the plane must climb to 10 000 m during the first 200 km. Then it must descend 10 000 m during the final 300 km. a) How much distance do the climb and descent add to the flight? b) The airplane averages a speed of 600 km/h. Do climbing and descending 10 000 m add hours, minutes, or seconds to the flight?
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
An airplane travels about 1500 km in a
straight line between Toronto and
Winnipeg. However, the plane must climb
to 10 000 m during the first 200 km. Then
it must descend 10 000 m during the final
300 km.
a) How much distance do the climb and
descent add to the flight?
b) The airplane averages a speed of
600 km/h. Do climbing and descending
10 000 m add hours, minutes, or
seconds to the flight? Explain.
