Alejandro's work:
t = number of hours for the pick-up truck driver to complete the trip
Equation: 55(21)-23-45(8)
Which statements identify Alejandro's errors? Check all that apply.
He should have added the 23 to the motorcyclist's distance instead of subtracting to balance the equation.
O He should have written 45(21) for the pick-up truck driver's distance, since the he took twice as long.
He should have written 55(t) for the motorcyclist's distance since t = number of hours for the pick-up truck driver to
complete the trip.
He should have written
for the motorcyclist's distance since it only took half the time as the pick-up truck driver.
He should have translated the scenario as motorcycle distance + pick-up truck distance = 23 since 23 is the distance
mentioned.
