Problema Solution
Write an equation in the form y=mx for the following situation. Then give the three ordered pairs associated with the equation for x-values of 0,5 and 10. x represents the time spent traveling at 65 mph and y represents the distance traveled in miles.
Answer provided by our tutors
the distance y travelled in miles is equal to the product of the speed in mile per hour (in this problem, the speed = 65 mph) and the time x spent travelling in hours
hence, y = 65x, where x is calculated in hours
for x = 0.5
=> y = 65 x 0.5 = 32.5 (miles)
=> (x, m, y) = (0.5, 65, 32.5)
for x = 10
=> y = 65 x 10 = 650 (miles)
=> (x, m, y)= (10, 65, 650)
