Issa is driving to the airport to catch a flight to Miami, and her arrival depends on traffic. If the traffic is light, then she can drive 60 mph and arrive at the airport 1 hour early. If traffic is heavy, she can drive 35 mph and arrive at the airport on time. The equation below models this situation, where t represents Issa's driving time in hours. 60(t-1) = 35t What is the distance, in miles, from Issa's hourse to the airport?
Please explain to solve. Thanks
solve for t: t=12/5
so, how far can she drive in 12/5 hours at 35mph?
It'll be the same as she can drive in 7/5 hours at 60 mph.
