Answer» Answer: The 65 tells us the constant speed the car is travelling at. The car travels 97.5 miles in 1.5 hours 0.4 of an hour to travel 26 miles Step-by-step explanation: d is the DISTANCE, we GET that by multiplying speed and time, we are told t is time, so 65 must be speed Substitute in 1.5 into the equation as the t, time d=65t d=65×1.5 d=97.5 The car takes 0.4 hours to travel 26 miles, substitute in 26 as the d, and isolate t to get the time it takes to travel 26 miles d=65t 26=65t 26÷65=t 0.4=t |
