Jade and her roommate Jari commute to work each morning, traveling west on I-10. One morning Jade left for work at 6:50 A.M., but Jari left 10 minutes later. Both drove at a constant speed. The following graphs show the distance (in miles) each of them has traveled on I-10 at time t (in minutes), where t = 0 is 7:00 A.M. y 30 Jade Distance 20 travled (mi) (6, 16) 10 Jari (6, 7) 4 6 8 10 12 Time Since 7:00 A.M. (min) (a) Use the graph to decide which of them is traveling faster. O Jade O Jari (b) Find the speed (in mi/h) at which each of them is driving. Jari mi/h Jade mi/h (c) Find linear functions fand g that model the distances that Jade and Jari travel as functions oft (in minutes). Jari d(t) = Jade d(t) =
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.
